Answer the following question.
A water tank has a capacity of 4000 gallons. Mack connects a pipe to the tank that fills the tank with water at the rate of 10 gallons per hour. How long will it take to fill the tank to 3/4 of its capacity?
Step-by-step reasoning process: 3 / 4 of the water tank is 3 / 4 * 4000 = 3000. If the pipe fills the tank with water at the rate of 10 gallons per hour, it will take 3000 / 10 = 300 hours to fill the tank to 3 / 4 of its capacity.
The answer is 300.

Answer the following question.
James was 2/3s as tall as his uncle who is 72 inches. He gets a growth spurt that makes him gain 10 inches. How much taller is his uncle than James now?
Step-by-step reasoning process: He was 72 * 2 / 3 = 48 inches tall before. He is now 48 + 10 = 58 inches. So his uncle is 72 - 58 = 14 inches taller.
The answer is 14.

Answer the following question.
Mr. and Mrs. McPherson have to renew their rent by the end of the year. They agreed that Mrs. McPherson would raise 30% of the money. If their rent is $1200 per year, how much does Mr. McPherson need to raise to complete the rent?
Step-by-step reasoning process: 30% of $1200 is (30 / 100) * $1200 = $360. Mrs. McPherson will pay $360 leaving $1200 - $360 = $840 which Mr. McPherson will have to raise.
The answer is 840.

Answer the following question.
Berry wants to make sure he reads an average of 50 pages a day. This week he read 43 pages on Sunday, 65 pages on Monday, and 28 pages on Tuesday. He had a soccer game and fell asleep early on Wednesday so he read nothing. On Thursday he read 70 pages, and on Friday he read 56 pages. How many pages does he have to read on Saturday to reach his goal?
Step-by-step reasoning process: He has to read 350 pages a week because 7 x 50 = 350. He has read 262 pages because 43 + 65 + 28 + 70 + 56 = 262. He has to read 88 pages on Saturday because 350 - 262 = 88.
The answer is 88.
