Question

1. Assume the pond starts with 500 frogs. For this problem, our unit of population will be a kiloFrog (= 1,000 frogs), so the initial population would be 0.5 kF. Write an equation that represents the number of frogs that will be in the pond next year if we assume that on average there will be two new frogs for each existing frog. No frogs die.

Answer 1

if there are 2 new frogs, then that means the population has tripled.

After t years, there will be

P(t) = 0.5 * 3^t kF
