Question

The population of West Algebra can be modeled by the equation

P = 30. 1.04^T, where T is the number of years since 2000 and P is
the population in millions. How many million people will there be
in 2020?
(1) 63.7 (2) 64.7
(3) 65.7
(4) 66.7

Answer 1

65.7

Explanation:

Given the population of West Algebra can be modeled by the equation

P = 30. 1.04^T

If T is the number of years since 2000 and P is the population in millions, in 2020, T = 2020 - 2000 = 20

Substitute T = 20 into the expression and get T

P = 30. 1.04^20

P = 30(2.1911)

P = 65.73

Hence the amount of people that will be there in 2020 is 65.7million people
