In 2006, the population of a country was 50 million and growing at the rate of 1.8% per year. Assuming the percentage growth rate remains constant, express the population, P (in millions), as a function of t, the number of years after 2006.
Hello, asweet1!
In 2006, the population of a country was 50 million and growing at the rate of 1.8% per year.
Assuming the percentage growth rate remains constant, express the population, (in millions),
as a function of , the number of years after 2006.
If the population increases at a rate of 1.8% per year,
. . each year's population is 1.018 times the previous year's population.
This is identical to a compound interest problem.
The function is: .
