One weekend Greg and Darius shoveled snow to earn spending money. Together they earned $12.50 an hour for 9 hours of work. Each received half the total earnings. If Greg then spent $15 on a new CD, what was the total amount he had left, in dollars and cents, from the money he earned shoveling snow that weekend?

A water tank contains 2,500 gallons. A faucet attached to the tank releases water at a constant rate of 5 gallons per minute. If the faucet is left open for 1 hour and no other water is released, which equation can be used to find r, the number of gallons of water remaining in the tank?

• r = 2,500 ÷ 5

• r = 2,500 - 60

• r = 2,500 - 60(5)

• r = 2,500 ÷ 60(5)
