# Population A population grows exponentially at a rate of 1.85%. How long will it take the population to double?

To determine

To calculate: The time required for the population to double if it grows exponentially at a rate of 1.85%.

Explanation

Given: Population grows exponentially at a rate of 1.85%.

Formula used:

The exponential growth model P=Cekt

Here C is the initial value of P, t is the time taken and k is the annual rate.

Calculation:

Consider the expression P=Cekt â€¦â€¦ (1)

The annual rate is k=1.85100.

The final population will be double the initial population, implies that P=2C
