1. A 250-gallon above-ground tank is slowly leaking water through a crack in one of
its sides. The amount of water (A, in gallons) that leaks out of the tank over a
period of t hours can be found using A = 2.5(t). If the tank was filled to the top at
8 AM, how much water would remain in the tank at 6 PM? Assume the rate of
leaking remained constant and no additional water was lost through any other
means.
