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?

5% of $2000 is (5/100)*$2000 = $

<<5/100*2000=100>>100 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? 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. Together, Aaron and his sister have a total age of 45+15 = <<45+15=60>>60 years Henry is four times as old as the sister, meaning he is 45*4 = <<45*4=180>>180 years old. 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? 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 Then use the same process to find how much sodium is in the salt: 50 mg/tsp * 2 tsp = <<50*2=100>>100 mg 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 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 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? Each episode takes 20*.5=<<20*.5=10>>10 minutes longer to film than it is So it takes 20+10=<<20+10=30>>30 minutes They are filming 5*4=<<5*4=20>>20 episodes So it takes 20*30=<<20*30=600>>600 minutes 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? Javier = 50 * 7 = <<50*7=350>>350 minutes Sanda = 90 * 3 = <<90*3=270>>270 minutes Total = 350 + 270 = <<350+270=620>>620 minutes 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? Mon, Wed, Fri she gets a $2.00 orange creamsicle so that's 3 days * $2/day = $<<3*2=6.00>>6.00 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 Sat and Sun she gets a $3.00 nutty-buddy so that's 2 days * $3/day = $<<2*3=6.00>>6.00 In one week she spends $6 + $3 + $6 = $<<6+3+6=15.00>>15.00 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? First find the time to drive to the airport: 10 minutes * 5 = <<10*5=50>>50 minutes Then find the time it takes to get through security: 15 minutes * 3 = <<15*3=45>>45 minutes Then find the time Mary spends waiting for the plane to take off: 20 minutes * 2 = <<20*2=40>>40 minutes 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 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 Dave bought 3 packs of white T-shirts and 2 packs of blue T-shirts for his basketball team. The white T-shirts come in packs of 6, and the blue T-shirts come in packs of 4. How many T-shirts did Dave buy in all? Dave bought 3 packs of white shirts * 6 = <<3*6=18>>18 white shirts. Dave bought 2 packs of blue shirts * 4 = <<2*4=8>>8 blue shirts. Dave bought a total of 18 + 8 shirts = <<18+8=26>>26 shirts. #### 26 My mother celebrated her birthday with a total of 60 guests. Half of the guests are women, 15 are men, and the rest are children. In the middle of the celebration, 1/3 of the men and 5 children left. How many people stayed and enjoyed the birthday celebration? There were 60 guests / 2 = <<60/2=30>>30 women at my mother's birthday celebration. There were 30 women + 15 men = <<30+15=45>>45 men and women. So, 60 people - 45 men and women = <<60-45=15>>15 were children. Then, 15 men / 3 = <<15/3=5>>5 men left. Thus, 5 men + 5 children = 10 people left. Therefore, 60 people - 10 people = <<60-10=50>>50 people stayed and enjoyed the birthday celebration. #### 50 Allen ordered five boxes of pizza, which cost $7 each box. He then gave a tip which amounts to 1/7 of the total cost of his order. If he gave the delivery man $100, how much change did he receive? The total cost of five boxes of pizza is $7 x 5 =$<<7*5=35>>35. He gave $35 x 1/7 = $<<35*1/7=5>>5 tip to the delivery man. He spent a total of $35 + $5 = $<<35+5=40>>40 for the pizza and the tip. The change that he received is $100 - $40 = $<<100-40=60>>60. #### 60
