Suppose that you turn on the hot water, which flows at 8.7 liters per minute into the bathtub. Two minutes later you also turn on the cold water, which flows at 13.2 liters per minute. Let x be the number of minutes since you turned on the cold water.
A. Write expressions in terms of x for the number of minutes the hot water has been running, the number of liters the hot faucet has delivered, and the number of liters the cold faucet has deliv- ered.
B. Write an equation stating that the hot and cold faucets have de- livered the same number of liters. Solve the equation to find out when this happens.
C. The tub holds 100 liters. Will it have overflowed by the time the hot and cold faucets have delivered the same amounts? Justify your answer.
