[Question]Jenna is on a road trip. She drives for 2 hours at 60mph. She takes a bathroom break, and then she continues driving for 3 hours at 50 mph. She can drive for 30 miles on one gallon of gas. If one gallon of gas costs $2, how much money does she spend on gas for her trip?
[Answer]First she drives 2 hours * 60 mph = 120 miles. Then she drives 3 hours * 50 mph = 150 miles. The total miles driven is 120 + 150 = 270 miles. Jenna uses 270 / 30 = 9 gallons of gas. The cost of gas is 9 * $2 = $18. The answer is 18.

Question: Ben will receive a bonus of $1496. He chooses to allocate this amount as follows: 1/22 for the kitchen, 1/4 for holidays and 1/8 for Christmas gifts for his 3 children. How much money will he still have left after these expenses?
Answer: Ben's spending for the kitchen is $1496 x 1 / 22 = $68. Ben's spending for holidays is $1496 x 1 / 4 = $374. Ben's spending for children's gifts is $1496 x 1 / 8 = $187. The total amount spent is $68 + $374 + $187 = $629. So, Ben still has $1496 - $629 = $867 left. The answer is 867.
[Question]Trevor is currently 11 years old and his older brother is 20 years old. How old will Trevor be when his older brother is three times as old as Trevor is now?
[Answer]When Trevor is 11, his older brother will be 11 x 3 = 33 years old. Trevor’s older brother is 20 - 11 = 9 years older than Trevor. Since Trevor is 9 years younger, Trevor will be 33 - 9 = 24 years old. The answer is 24.
Q: Mary is counting the number of minnows in the pond. 40% of the minnows have red bellies, 30% have green bellies and the rest have white bellies. If 20 minnows have red bellies, how many minnows have white bellies?
A: First find the total number of minnows by dividing the number of red minnows by the percentage of minnows that are red: 20 minnows / 40% = 50 minnows. Then subtract the percentages of red - and green - bellied minnows to find the percentage of white - bellied minnows: 100% - 40% - 30% = 30%. Then multiply the total number of minnows by the percentage that have white bellies: 30% * 50 minnows = 15 minnows. The answer is 15.
Question: Billy's family likes to keep their bicycles stored in the garage when they're not being used. They own a total of 4 bicycles. Each bicycle wheel has 10 spokes. How many spokes are inside the garage?
Answer:
Each bicycle has 2 wheels, so there are a total of 4 * 2 = 8 wheels in the garage as there are 4 bicycles. Since each wheel has 10 spokes, this means there are 8 * 10 = 80 spokes in total. The answer is 80.
