Question

A population increases from 13,000 at an annual rate of 4% a year. Which function would model this?

A.
P(t) = 13,000(0.04)
B.
P(t) = 13,000(0.4)*
C.
P(t) = 13,000(1.04)*
D.
P(t) = 13,000(1.4)*

Answer 1

A 4% increase is equal to 1.04 as a decimal.

This means the answer is C.

P(t) = 13,000(1.04)

This can also be written as 13000 x 1.04
