Question

Prompt

An exponential model for the number of squirrels in a certain area estimates that there were

200

squirrels in the area in the year

2003

, and that at the end of each

4

-year period for the next

20

years, the number of squirrels in the area was

120%

more than the number at the end of the previous

4

-year period. Which of the following equations represents this model, where

N

is the estimated number of squirrels in this area

t

years after

2003

, and

0 \leq t \leq 20

N = 200 (2.20)^{4 t}

N = 200 (1.20)^{4 t}

N = 200 (1.20)^{\frac{t}{4}}

N = 200 (2.20)^{\frac{t}{4}}
