A pond has a minnow population of 20000 that is increasing at a rate of 5%
per year. The minnows' algae food supply is decreasing so that it supports
750 less minnows each year. How is the population of minnows growing,
and how is the supply of algae declining?

20000x.05= 1000 added minnows per year, with the algae decline, we loose 750 minnows per year. 250 minnows are added every year. The rate 5% every year would be exponential growth, and the decline of 750 minnows per year is a result of a negative constant (not exponential decline.)
