Answer:
The population grew by 4,620 people.
Explanation:
First, convert the percent into a decimal.
7/100=0.07 <- this is 7% as a decimal.
Now take the population number, 66,000, and multiply it by 107% (convert this to a decimal using the same formula as before and you'll get 1.07.)
66,000x1.07=70,620
Now subtract to find the growth.
70,620-66,000=4,620
