Question

The enrollment at a nearby college was 28,000 in 2010. It is decreasing at a rate of 1.1% each

year. What will the enrollment be in 2030

Answer 1

22443

Explanation:

formula: ab^x

a= starting amount b=exponential decrease x= amount of years

r= rate b= 1-r

a= 28000 b=1-0.011= 0.989 x= 2030-2010= 20 (years)

r= 1.1%= 0.011

Plug into formula:

ab^x

28000(0.989 )^20

= 22443.152645

= 22443
