Kerri is draining her 35-gallon fish tank so that she will be able to clean it. The graph represents the number of gallons that are being drained over hours in time. Immediately after Kerri begins draining the tank, she goes on a run for two hours, then spends one hour making herself lunch. Assuming that it takes Kerri 30 minutes to eat lunch, how much water will still be left in the tank when she goes to check on it after lunch?

Slope = (20−35)/(5−0) = −3 gal/hr. Water left after t hours: 35 − 3t. Time until she checks = 2 + 1 + 0.5 = 3.5 hr.
35 − 3(3.5) = 35 − 10.5 = 24.5 gallons.
