Question: James gets paid $0.50/mile to drive a truck carrying hazardous waste. He has to pay $4.00/gallon for gas and his truck gets 20 miles per gallon. How much profit does he make from a 600 mile trip?
Answer: First find the total payment James receives: $0.50 / mile * 600 miles = $300. Then find how many gallons of gas he needs to buy: 600 miles / 20 miles / gallon = 30 gallons. Then multiply that number by the price of gas per gallon to find the total cost of the gas: $4.00 / gallon * 30 gallons = $120. Then subtract that amount from James' earnings to find his profit: $300 - $120 = $180. The answer is 180.

[Answer]He needs 12 tablespoons of lemon juice for every dozen of cupcakes and he’s making 3 dozen cupcakes so he needs 12 * 3 = 36 tablespoons of lemon juice. 1 lemon provides 4 tablespoons of lemon juice and he needs 36 tablespoons so he will need 36 / 4 = 9 lemons. The answer is 9.
Q: On Tuesday, Liza had $800 in her checking account. On Wednesday, she paid her rent, $450. On Thursday, she deposited her $1500 paycheck. On Friday, she paid her electricity and internet bills which were $117 and $100, respectively. Then on Saturday, she paid her phone bill, $70. How much money is left in Liza's account?
A: On Wednesday, Liza had $800 - $450 = $350 left in her account. After depositing on Thursday, she had $350 + $1500 = $1850 in her account. On Friday, she paid a total of $117 + $100 = $217 for her electricity and internet bills. So, $1850 - $217 = $1633 was left on her account on Friday. After paying her phone bill, Liza has $1633 - $70 = $1563 left in her account. The answer is 1563.
Question: When Betty makes cheesecake, she sweetens it with a ratio of one part sugar to four parts cream cheese, and she flavors it with one teaspoon of vanilla for every two cups of cream cheese. For every one teaspoon of vanilla, she uses two eggs. She used two cups of sugar in her latest cheesecake. How many eggs did she use?
Answer: Betty used 2 cups of sugar in her cheesecake, so she used 2 * 1 = 2 times her ratio. Thus, she used 2 * 4 = 8 cups of cream cheese. She uses 1 teaspoon of vanilla for 2 cups of cream cheese, so she used 8 / 2 = 4 teaspoons of vanilla. For each teaspoon of vanilla, she uses 2 eggs, so she used 2 * 4 = 8 eggs. The answer is 8.
[Question]John has taken 10 pictures every day for the past 3 years. He saves them in raw format so each memory card can store 50 images. Each memory card costs $60. How much does he spend on memory cards?
[Answer]He takes pictures for 3 * 365 = 1095 days. So he takes 10 * 1095 = 10,950 pictures. That means he needs 10950 / 50 = 219 memory cards. So he spends 219 * 60 = $13140 on memory cards. The answer is 13140.
[Question]Lisa and Carly go shopping together. Lisa spends $40 on t-shirts then spends half of this amount on jeans and twice this amount on coats. Carly spends only a quarter as much as Lisa on t-shirts but spends 3 times as much on jeans and a quarter of the amount Lisa spent on coats. In dollars, how much did Lisa and Carly spend in total?
[Answer]
Lisa spends $40 on t - shirts / 2 = $20 on jeans. She also spends $40 on t - shirts * 2 = $80 on coats. So Lisa has spent a total of 40 + 20 + 80 = $140. Carly spends $40 / 4 = $10 on t - shirts. She also spends $20 per pair of jeans * 3 = $60 on jeans. She then also spends $80 Lisa’s cost for coats / 4 = $20 on coats. So Carly has spent a total of 10 + 60 + 20 = $90. Lisa and Carly have therefore spent a total of 140 + 90 = $230. The answer is 230.
