Suppose that the population of deer in a state is 1,500 and is growing 2% each year. Predict the population after 4 years.
a
about 1,624 deer
b
about 3,110 deer
c
about 24,000 deer
d
about 12,000 deer
The correct answer is d. about 12,000 deer.
After 1 year: 1,500 * 1.02 = 1,530
After 2 years: 1,530 * 1.02 = 1,561.2
After 3 years: 1,561.2 * 1.02 = 1,593.424
After 4 years: 1,593.424 * 1.02 = 1,625.28248
Therefore, the predicted population after 4 years is about 1,625 deer, which is closest to 1,624 deer.
