A basement is flooded with 400 cubic feet of water. Each hour, 50 cubic feet of water is pumped out of the basement.
a. Complete Table 37 to help find an expression that stands for the volume (in cubic feet) of water in the basement after water has been pumped out for t hours. Show the arithmetic to help you see a pattern.

b. Evaluate the expression that you found in part (a) for t = 7. What does your result mean in this situation?
