The income I, in dollars per month, for a fish farm depends on the fish population 
, measured in hundreds of fish. The relationship is
.
A: Make a graph of I versus n for fish populations up to 15 hundred fish.B: The expense E, in dollars per month, also depends on the population (again measured in hundreds). The relationship is
.
Add the graph of E versus n to the graph you made in part A.C: The fish farm is profitable if income exceeds expenses. What range of fish population results in a profitable fish farm?
