On Monday a group of 7 children and 5 adults went to the zoo. On Tuesday a group of 4 children and 2 adults went as well. Child tickets cost $3, and adult tickets cost $4. How much money did the zoo make in total for both days?

How many children went on both days? ** The total amount of children that went on both days is 7 + 4 =

<<7+4=11>>11. How much did the children's tickets cost? ** The cost of the children's tickets is 11 × $3 = $<<11*3=33>>33. How many adults went on both days? ** The total amount of adults that went on both days is 5 + 2 = <<5+2=7>>7. How much did the adults' tickets cost? ** The cost of the adults' tickets is 7 × $4 = $<<7*4=28>>28. How much money did the zoo make in total for both days? ** The zoo made $33 + $28 = $<<33+28=61>>61 in total. #### 61 Marj has two $20 bills, three $5 bills, and $4.50 in loose coins in her wallet. If she buys a cake that costs $17.50, how much money will be left in her wallet? How much money does Marj have? ** Two $20 bills amount to $20 x 2 = $<<20*2=40>>40. How much money does Marj have? ** Three $5 bills amount to $5 x 3 = $<<5*3=15>>15. How much money does Marj have? ** So, Marj has $40 + $15 + $4.50 = $<<40+15+4.5=59.50>>59.50 in her wallet. How much money will be left in her wallet? ** If she buys a cake, she will be left with $59.50 - $17.50 = $<<59.5-17.5=42>>42. #### 42 Legacy has 5 bars of gold she received from her father. Her friend Aleena has 2 bars fewer than she has. If a bar of gold is worth $2200, calculate the total value of gold the three have together. How many bars does Aleena have? ** If Legacy has 5 bars, Aleena has 5 bars - 2 bars = <<5-2=3>>3 bars. How many bars do they have together? ** In total, they have 5 bars + 3 bars = <<5+3=8>>8 bars, How much are the 8 bars together worth? ** Since one bar of gold is worth $2200, the 8 bars they have together are worth 8 bars * $2200/bar = $<<8*2200=17600>>17600 #### 17600 Without factoring in the cost of depreciation for his car John made $30,000 doing Uber. When he finally traded in the car he bought for $18,000 he got $6000 back. What was his profit from driving Uber? How much did John's car depreciate? ** His car depreciated 18000-6000=$<<18000-6000=12000>>12000 How much did John make in profit? ** So he made a profit of 30000-12000=$<<30000-12000=18000>>18000 #### 18000 Zoe wants to go on the field trip to Washington DC with her middle school this spring and the cost is $485. Her grandma gave her $250 toward her fees and she must earn the rest by selling candy bars. She makes $1.25 for every candy bar she sells. How many candy bars does Zoe need to sell to earn the money for the trip? How much money does Zoe need to earn? ** Since Zoe’s grandma gave her some money toward her trip, she needs to come up with $485 – $250 = $<<485-250=235>>235. How many candy bars does Zoe need to sell? ** This means she must sell $235 / $1.25/candy bar = <<235/1.25=188>>188 candy bars. #### 188 Henley bought 300 candies and shared them with her two brothers. However, they realized 40% of them were sour, and they had to separate those out. If they then shared the good candies equally, how many candies did each get? How many sour candies were there? ** If the number of candies was 300, and 40% percent were sour, then there were 40/100*300 =<<40/100*300=120>>120 sour candies. How many good candies were there? ** The number of good candies was 300-120=<<300-120=180>>180 How many people received candy? ** The number of people who received candy is Henley, 1+ 2 brothers = <<1+2=3>>3 people How many candies did each person get? ** if they divided the good candies equally, each person got 180/3 = <<180/3=60>>60 candies. #### 60 A store decides to shut down and sell all of its inventory. They have 2000 different items which would normally retail for $50. They are offering an 80% discount and manage to sell 90% of the items. They owed $15000 to their creditors. How much money do they have left after the sale? How many items did they sell? ** They sold 2000*.9=<<2000*.9=1800>>1800 items How much did they discount the items? ** They offered a 50*.8=$<<50*.8=40>>40 discount How much did each item sell for? ** That means that each item sold for 50-40=$<<50-40=10>>10 How much money did they make? ** So they made 1800*10=$<<1800*10=18000>>18,000 How much money did they have left after the sale? ** So they had 18,000-15,000=$<<18000-15000=3000>>3,000 leftover #### 3000 Ben's potato gun can launch a potato 6 football fields. If a football field is 200 yards long and Ben's dog can run 400 feet/minute, how many minutes will it take his dog to fetch a potato he launches? How far does the potato fly? ** First find the total distance the potato flies in yards: 200 yards/field * 6 fields = 1200 yards How far does the potato fly? ** Then multiply that number by the number of feet per yard to convert it to feet: 1200 yards * 3 feet/yard = <<1200*3=3600>>3600 feet How many minutes will it take his dog to fetch a potato he launches? ** Then divide that number by the dog's speed to find the number of minutes it has to run to fetch the potato: 3600 feet / 400 feet/minute = <<3600/400=9>>9 minutes #### 9 During a staff meeting, 50 doughnuts were served. If each of the 19 staff ate 2 doughnuts, how many doughnuts are left? How many doughnuts did the staff eat? ** The staff had eaten a total of 19 x 2 = <<19*2=38>>38 doughnuts. How many doughnuts are left? ** So, 50 - 38 = <<50-38=12>>12 doughnuts are left. #### 12 Al is 25 pounds heavier than Ben. Ben is 16 pounds lighter than Carl. If Ed weighs 146 pounds and is 38 pounds lighter than Al, find the weight of Carl. How much does Al weigh? ** Al weighs 146 + 38 = <<146+38=184>>184 pounds. How much does Ben weigh? ** Ben weighs 184 - 25 = <<184-25=159>>159 pounds. How much does Carl weigh? ** Carl weighs 159 + 16 = <<159+16=175>>175 pounds. #### 175
