Select the correct answer from the drop-down menu. The size of a population, P, can be calculated with this equation.
P = Po(1 + r)
In the equation, Po represents the initial population size, rrepresents the population's growth rate, and t represents the time in years.
A population of frogs in a pond currently has 50 individuals and grows at a rate of 30 percent per year. It will take this
population approximately
years to double in size.
