Carolyn has a 20-gallon fish tank. Each hour it is leaking 10 ounces. Write an equation to show how long the water will last. (20-gallons is 2560 ounces)

20 - 10h = 0
10h = 20
2560 - 10h = 0
2560 + 10h = 0

2560 - 10h = 0

Explanation: start with 2560 ounces and subtract 10 ounces per hour; set equal to 0 to find when it's empty. Solve: 10h = 2560 ⇒ h = 256 hours (which is 10 days and 16 hours).
