Answer:
810,045
Explanation:
The population growth equation can be written using the doubling time as ...
P = p(2^(t/d)) . . . where p is the current population, d is the doubling time
Application
For the given numbers, the equation becomes ...
P = 750,000(2^(4/36)) ≈ 810,045
In 4 years, the population will be about 810,045.
