[Question]Brooke is milking cows and then selling the milk at the market for $3 a gallon. Whatever milk doesn't sell, she turns into butter. One gallon of milk equals 2 sticks of butter. She then sells the butter for $1.5 a stick. She has 12 cows. Each cow produces 4 gallons of milk. She has 6 customers, each of whom wants 6 gallons of milk. How much money does she earn if she sells all her milk and butter?
[Answer]A gallon of milk makes $3 worth of butter because 2 x 1.5 = 3. A gallon of milk sells for the same amount as milk or butter because 3 = 3. She gets 48 gallons of milk because 4 x 12 = 48. She earns $144 selling the milk because 48 x $3 = 144. The answer is 144.
Q: A fifth-grade class went on a field trip to the zoo, and their class of 10 students merged with another class with the same amount of students. 5 parents offered to be a chaperone, and 2 of the teachers from both classes will be there too. When the school day was over, the students could choose to go home and 10 of them left. Two of the chaperones were parents in that group, so they left as well. How many individuals were left at the zoo?
A: A total of 10 * 2 = 20 students went on the field trip. Some chaperones showed up, letting the group grow to 20 + 5 = 25 individuals. The teachers had to come as well, making the group as big as 25 + 2 = 27 individuals. When the school day ended, 27 - 10 = 17 individuals were left. A couple of chaperones followed suit, leaving 17 - 2 = 15 people at the zoo. The answer is 15.
Question: If Jenna has twice as much money in her bank account as Phil does, and Phil has one-third the amount of money that Bob has in his account, and Bob has $60 in his account, how much less money does Jenna have in her account than Bob?
Answer: If Phil has one - third of the amount that Bob does, that means he has $60 / 3 = $20 in his account. Since Jenna has twice as much money as Phil, that means she has $20 * 2 = 40 in her account. Since Bob has $60 in his account, that means he has $60 - $40 = $20 more than Jenna. The answer is 20.
[Question]Woody wants to buy a games console that costs $282. Woody already has $42 and receives an allowance of $24 every week. How many weeks will it take him to save the money he needs for the game console?
[Answer]Woody needs to save another $282 - $42 = $240 to be able to afford a games console. It will take Woody $240 / $24 / week = 10 weeks to save up enough money. The answer is 10.
Q: A school does a yearly tree planting activity. This year, the 4th graders planted a total of 30 trees while 5th graders planted twice as many. The 6th graders planted 30 fewer than thrice the number of trees planted by the 5th graders. How many trees did they plant altogether?
A: The 5th graders planted 30 x 2 = 60 trees. Thrice the number of trees planted by the 5th graders is 60 x 3 = 180. So, the 6th graders planted 180 - 30 = 150 trees. Therefore, they planted a total of 30 + 60 + 150 = 240 trees. The answer is 240.
Question: Mimi has decided to start going to the gym again. Over the weekend, she spent $8,000 on athletic sneakers and clothes. She spent thrice as much on Nike sneakers as she did on Adidas. What she spent on Adidas was 1/5 the cost of Skechers. If Mimi's Adidas sneakers purchase was $600, what amount did she spend on clothes?
Answer:
The Adidas purchase was 1 / 5 that of Skechers, therefore the Skechers cost 5 * 600 = 3000 dollars. Spending three times the cost of Adidas on Nike sneakers translates to 3 * 600 = 1800 dollars. All together, the three athletic - sneaker purchases cost Mimi 600 + 1800 + 3000 = 5400 dollars. Subtracting the amount spent on athletic sneakers from the total spent gives 8000 - 5400 = 2600 dollars. Mimi therefore spent 2600 dollars on clothes. The answer is 2600.
