GiGi took out a big bowl of mushrooms from the refrigerator. She cut each mushroom into 4 pieces. Her twins, Kenny and Karla sprinkled mushrooms on their pizzas and baked them in the oven. Kenny grabbed a handful and sprinkled 38 mushroom pieces on his pizza. Karla scooped them up with both hands and sprinkled 42 mushroom pieces on her pizza. On the cutting board, were 8 pieces of mushrooms remaining. How many mushrooms did GiGi cut up at the beginning?
How many mushrooms did Kenny use? ** Kenny used 38 / 4 =
<<38/4=9.5>>9.5 mushrooms on his pizza. How many mushrooms did Karla use? ** Karla used 42 / 4 = <<42/4=10.5>>10.5 mushrooms on her pizza. How many mushrooms did Kenny and Karla use together? ** Together, the twins used 9.5 + 10.5 = <<9.5+10.5=20>>20 mushrooms. How many mushrooms did GiGi cut up at the beginning? ** There are 8 / 4 = <<8/4=2>>2 mushrooms left on the cutting board. How many mushrooms did GiGi cut up at the beginning? ** GiGi cut up 20 + 2 = <<20+2=22>>22 mushrooms at the beginning. #### 22 Jason and Jeremy want to paint their wall white and agreed to split the cost of the paint. A gallon of paint costs $45 and can cover up to 400 square feet. How much will each of them contribute to the cost of the paint if their walls have a total area of 1600 square feet and will need a second coat? How many gallons of paint will they need? ** They need 1600 square feet / 400 square feet/gallon = <<1600/400=4>>4 gallons of paint for their walls. How many gallons of paint will they need in total? ** Since they will do a second coating, then they would need 4 gallons x 2 = <<4*2=8>>8 gallons in all. How much will the paint cost in total? ** Eight gallons of paint will cost $45/gallon x 8 gallons = $<<45*8=360>>360. How much will each of them contribute to the cost of the paint? ** Thus, Jason and Jeremy will each contribute $360/2 = $<<360/2=180>>180. #### 180 For breakfast, Anna bought a bagel for $0.95 and a glass of orange juice for $0.85. At lunch, Anna spent $4.65 on a sandwich and $1.15 on a carton of milk. How much more money did Anna spend on lunch than on breakfast? How much did Anna spend on breakfast? ** The total cost of breakfast is $0.95 + $0.85 = $<<0.95+0.85=1.80>>1.80. How much did Anna spend on lunch? ** The total cost of lunch is $4.65 + $1.15 = $<<4.65+1.15=5.80>>5.80. How much more money did Anna spend on lunch than on breakfast? ** Anna spent $5.80 − $1.80 = $4 more on lunch than breakfast. #### 4 Mr. John works at a shopping mall and receives a monthly income of $2000, but he spends approximately 5% of this amount on public transport to and from the mall in a month. How much will he have left after deducting his monthly transport fare from his income? How much does John spend on public transport? ** 5% of $2000 is (5/100)*$2000 = $<<5/100*2000=100>>100 How much will John have left after deducting his monthly transport fare from his income? ** After removing his transport fare, he will have $2000-$100 = $1900 left #### 1900 Aaron, Henry's brother, is 15 years old. Henry's sister is three times as old as Aaron. Henry is four times as old as his sister. What's the combined age of the siblings? How old is Henry's sister? ** If Aaron is 15 years old, and his sister is 3 times as old as him, then the sister is 3*15 = <<15*3=45>>45 years old. What's the combined age of the siblings? ** Together, Aaron and his sister have a total age of 45+15 = <<45+15=60>>60 years How old is Henry? ** Henry is four times as old as the sister, meaning he is 45*4 = <<45*4=180>>180 years old. What's the combined age of the siblings? ** The three siblings together have a total age of 60+180 = <<60+180=240>>240 years #### 240 James is trying to avoid eating too much sodium. He's making a recipe that calls for 2 teaspoons of salt and 8 oz of parmesan cheese. Salt has 50 mg of sodium per teaspoon and parmesan has 25 mg of sodium per oz. If he can't reduce the salt, how many fewer ounces of parmesan cheese does he need to use to reduce the total amount of sodium by 1/3rd? How much sodium is in the parmesan? ** First find how much sodium the parmesan has in total by multiply the amount of sodium per ounce by the number of oz: 25 mg/oz * 8 oz = <<25*8=200>>200 mg How much sodium is in the salt? ** Then use the same process to find how much sodium is in the salt: 50 mg/tsp * 2 tsp = <<50*2=100>>100 mg How much sodium is in the recipe? ** Then find the total sodium in the recipe by adding the sodium from the cheese and the salt: 100 mg + 200 mg = <<100+200=300>>300 mg How much less sodium does James want? ** Then multiply the total amount of sodium by 1/3 to find how much less sodium James wants: 300 mg * 1/3 = <<300*1/3=100>>100 mg How many fewer ounces of cheese does James need? ** Then divide this amount by the amount of sodium per ounce of cheese to find how many fewer ounces of cheese he needs: 100 mg / 25 mg/oz = <<100/25=4>>4 oz #### 4 Tim host a show and they film multiple episodes per day. Each episode is 20 minutes long and it takes 50% longer than that to film each episode. Each week they show 5 episodes. How many hours would it take to film 4 weeks of episodes? How many minutes does each episode take longer than it is? ** Each episode takes 20*.5=<<20*.5=10>>10 minutes longer to film than it is How many minutes does each episode take? ** So it takes 20+10=<<20+10=30>>30 minutes How many episodes are they filming? ** They are filming 5*4=<<5*4=20>>20 episodes How many minutes does it take to film 4 weeks of episodes? ** So it takes 20*30=<<20*30=600>>600 minutes How many hours would it take to film 4 weeks of episodes? ** This is equivalent to 600 / 60 = <<600/60=10>>10 hours #### 10 Javier exercised for 50 minutes every day for one week. Sanda exercised for 90 minutes on each of three days. How many minutes did Javier and Sanda exercise in total? How many minutes did Javier exercise in total? ** Javier = 50 * 7 = <<50*7=350>>350 minutes How many minutes did Sanda exercise in total? ** Sanda = 90 * 3 = <<90*3=270>>270 minutes How many minutes did Javier and Sanda exercise in total? ** Total = 350 + 270 = <<350+270=620>>620 minutes How many minutes did Javier and Sanda exercise in total? ** Together Javier and Sanda exercised for 620 minutes. #### 620 For 6 weeks in the summer, Erica treats herself to 1 ice cream cone from the ice cream truck. Monday, Wednesday and Friday she gets a $2.00 orange creamsicle. Tuesday and Thursday she gets a $1.50 ice cream sandwich. Saturday and Sunday she gets a $3.00 Nutty-Buddy. How much money does she spend on ice cream in 6 weeks? How much does she spend on orange creamsicles? ** Mon, Wed, Fri she gets a $2.00 orange creamsicle so that's 3 days * $2/day = $<<3*2=6.00>>6.00 How much does she spend on ice cream sandwiches? ** Tue and Thur she gets a $1.50 ice cream sandwich so that's 2 days * $1.50/day = $<<2*1.5=3.00>>3.00 How much does she spend on nutty-buddies? ** Sat and Sun she gets a $3.00 nutty-buddy so that's 2 days * $3/day = $<<2*3=6.00>>6.00 How much does she spend in one week? ** In one week she spends $6 + $3 + $6 = $<<6+3+6=15.00>>15.00 How much does she spend in 6 weeks? ** Over 6 weeks she spends 6 weeks * $15/week = $<<6*15=90.00>>90.00 #### 90 Mary is going on a business trip. It takes 10 minutes for her Uber to get to her house and 5 times longer to get to the airport. It takes 15 minutes to check her bag and three times as long to get through security. Then she has to wait for 20 minutes for her flight to start boarding and twice as long before the plane is ready to take off. How many hours will this process take total? How many minutes does it take to drive to the airport? ** First find the time to drive to the airport: 10 minutes * 5 = <<10*5=50>>50 minutes How many minutes does it take to get through security? ** Then find the time it takes to get through security: 15 minutes * 3 = <<15*3=45>>45 minutes How many minutes does Mary spend waiting for the plane to take off? ** Then find the time Mary spends waiting for the plane to take off: 20 minutes * 2 = <<20*2=40>>40 minutes How many minutes does it take to get through the whole process? ** Then add the time to each step to find the total time: 10 minutes + 50 minutes + 15 minutes + 45 minutes + 20 minutes + 40 minutes = <<10+50+15+45+20+40=180>>180 minutes How many hours will this process take total? ** Then divide that amount by the number of minutes per hour to cover the total time to hours: 180 minutes / 60 minutes/hour = <<180/60=3>>3 hours #### 3
