A certain city has a population growth rate corresponding to the relationship P=pe^(0.05t) where P is the population after t years when p is the current population level (e is the natural number). How many years will it take for the city to double in population (round the the nearest year)?

Question

since you want P = 2p, replace that in your equation:
2p=pe^(0.05t)
2=e^(0.05t)

can you solve for t here?
