An isolated fish population is limited to 5000 by the amount of food available. If there are now 300 fish and the population is growing with a growth constant of 3% a year, find the expected population at the end of 20 years. Let the variable t represent time and y represent the population at time t. What is the equation for y that models the fish population? y = (Type an exact answer in terms of e.) Find the expected population at the end of t = 20 years using the equation for y. fish (Round to the nearest integer as needed.)
