Question: Donny went to the gas station to gas up his tank. He knows his truck holds 150 liters of fuel. His truck already contained 38 liters. How much change will he get from $350 if each liter of fuel costs $3?
Answer with step-by-step thinking: He needs 150 - 38 = 112 liters more to have a full tank of gas. Donny will pay 112 x $3 = $336 for a full tank of gas. His will get $350 - $336 = $14 change.".
So the answer is 14.


Question: James is trying to decide which trail is faster to hike. One trail is 20 miles and mostly downhill, so James can cover it at 5 miles per hour. The other trail is 12 miles, but it's mostly uphill, so James will only be able to cover 3 miles per hour and will have to take an hour break halfway through. How many hours faster is the fastest hike?
Answer with step-by-step thinking: First find how long the first trail takes to hike: 20 miles / 5 miles / hour = 4 hours. Then find how long James spends hiking the second trail: 12 miles / 3 miles / hour = 4 hours. Then add the 1 hour break James has to take on the second trail: 4 hours + 1 hour = 5 hours. Then subtract the time for the first trail from the time for the second trail to find the difference: 5 hours - 4 hours = 1 hour.
So the answer is 1.


Question: Jason is trying to figure out whether he can afford a new car. The car he wants costs $32,000, and he can make a down payment of $8,000. He'll have to get a loan for the rest of the amount and make 48 equal monthly payments on it. Each month, he also has to pay interest equal to 5% of that month's payment. How much will Jason's monthly payments be?
Answer with step-by-step thinking:

First figure out how much the loan will be: $32,000 - $8,000 = $24,000. Then divide the loan amount by the number of payments to find the monthly payment before interest: $24,000 / 48 months = $500 / month. Then multiply the loan amount by 5% to find out how much the interest is: $500 / month * .05 = $25 / month. Then add the interest to the payment amount to find the total monthly payment: $500 / month + $25 / month = $525 / month.
So the answer is 525.
