Eloise purchased a number of water hand pumps to give to a
charity. The mean (average) price was $85\$85 per water pump. If Eloise spent a
total of $765\$765, how many water
pumps did she purchase?

Eloise spent a total of $765\$765 and the mean price of each water
pump was $85\$85.

Thus, Eloise purchased $765$85=9\frac{\$765}{\$85}=9 water pumps.
