Isn't there a formula? I have never learned this type of problem.

Basically we can find the exponential growth model with the help of below formula:

a(t) = Ae^rt  

where,

A = population

r = rate of increase

t = time

Thank you for the formula, but don't I only have one of those unknowns?
