Lexie Duarte · Answer 1

The number of books increases at a rate of 6.49% each year so it's a growth function which is

V (t) = V0 (1+r) ^t

V (t) number of books in 2020?

V0 books in the year 1998 19000

R rate of growth 0.0649

T time 2,020-1,998=22 years

V (22) = 19,000 * (1+0.0649) ^ (22)

V (22) = 75,778.81 Round your answer to get 75779
