[Question]: John rents a car to visit his family. It cost $150 to rent the car. He also had to buy 8 gallons of gas to fill it up and gas is $3.50 per gallon. The final expense is $.50 per mile. If he drove 320 miles how much did it cost?
[Answer]: The gas cost 8 * 3.5 = $28. The mileage expenses cost 320 * .5 = $160. So in total he paid 150 + 28 + 160 = $338.
So the answer is 338.

[Question]: Jane sews 2 dresses a day for 7 days. Then she sews 3 dresses a day for the next 2 days. In the end, she adds 2 ribbons to each dress. How many ribbons does Jane use in total?
[Answer]: In 7 days, Jane sews 2 * 7 = 14 dresses. In the next 2 days, Jane sews 3 * 2 = 6 dresses. Jane sews a total of 14 + 6 = 20 dresses. Jane uses a total of 20 * 2 = 40 ribbons.
So the answer is 40.

[Question]: Tim's cat bit him. He decided to get himself and the cat checked out. His doctor's visits $300 and insurance covered 75%. His cat's visit cost $120 and his pet insurance covered $60. How much did he pay?
[Answer]:
The insurance covers 300 * .75 = $225. So he had to pay 300 - 225 = $75. The cats visit cost 120 - 60 = $60. So in total he paid 75 + 60 = $135.
So the answer is 135.
