1. A population of tropical fish is decreasing at an annual rate of 6% per year. (a) Write an equation to represent the total population of tropical fish as a function of time in years. (b) What is the monthly rate of decrease? Show your work.

Respuesta :

The total population of tropical fish is given by P(t) = Po(1 - 0.06)^t = Po(0.94)^t
where Po is the initial population and t is the number of years.

The monthly rate = 6%/12 = 0.5%.
