Q: Lance has 70 cents, Margaret has three-fourths of a dollar, Guy has two quarters and a dime, and Bill has six dimes. How many cents do they have combined?
A: Margaret has 100 * 0.75 = $0.75. Guy has $0.25 + $0.25 + $0.10 = $0.60. Bill has 6 * $0.10 = $0.60. Lance, Margaret, Guy and Bill have $0.70 + $0.75 + $0.60 + $0.60 = $2.65. Thus they have $2.65 * 100 = 265 cents. The answer is 265.
Question: In 5 years, Raven will be 4 times as old as Phoebe. If Phoebe is currently 10 years old, how old is Raven?
Answer: In five years, Phoebe will be 10 + 5 = 15 years old. If Raven is four times as old as Phoebe in fifteen years, he will be 4 * 15 = 60 years old in 5 years. Currently, Raven is 60 - 5 = 55 years old. The answer is 55.
[Question]Bella has two times as many marbles as frisbees. She also has 20 more frisbees than deck cards. If she buys 2/5 times more of each item, what would be the total number of the items she will have if she currently has 60 marbles?
[Answer]When Bella buys 2 / 5 times more marbles, she'll have increased the number of marbles by 2 / 5 * 60 = 24. The total number of marbles she'll have is 60 + 24 = 84. If Bella currently has 60 marbles, and she has two times as many marbles as frisbees, she has 60 / 2 = 30 frisbees. If Bella buys 2 / 5 times more frisbees, she'll have 2 / 5 * 30 = 12 more frisbees. The total number of frisbees she'll have will increase to 30 + 12 = 42. Bella also has 20 more frisbees than deck cards, meaning she has 30 - 20 = 10 deck cards. If she buys 2 / 5 times more deck cards, she'll have 2 / 5 * 10 = 4 more deck cards. The total number of deck cards she'll have is 10 + 4 = 14. Together, Bella will have a total of 14 + 42 + 84 = 140 items. The answer is 140.

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.
