Question

The number of students in the book club is increasing at a rate of 15% per year. In 2010 there were 9 students in the book club. Find the number of students expected to be in the club in the year 2020. I just need help figuring out the equation.

Answer 1

N~[9*1,15^(2020-2010)]= [36,41]=36

Answer 2

i think the equation for this would be 9+1.35x
then i think you would have to round it after because you cant really have a third of someone.
