(Please help)
Suppose you turn a pump on and let it run to empty the water out of a pool. The amount of water in the pool (W, measured in gallons) at any time (T, measured in hours) is given by the following equation: W = -350 (T – 4).


1. How many gallons of water are being pumped out each hour?


2. Explain how you found the answer to number 2.


3. When the pump is placed in the pool, how much time has passed? (hint: you just started)


4. How much water was in the pool when the pumping started? (hint: at the beginning)


5. How long will it take for the pump to empty the pool? (hint: When the pool is empty which value should be zero?)

6. Write an equation that is equivalent to W = -350(T – 4). (hint: distribute and solve for T)


7. What does your new equation tell you about the situation?
