Question

The number of books donated to a library is increasing by 25% each month. Initially, there were 80 books donated to the library. There were 100 books donated at the end of Month 1. How many books are expected to be donated to the library at the end of Month 10?

Answer 1

Answer: 745

Step-by-step explanation: if there were initialy 80 books and its increasing by 25% every month, for month 1 we have:

25% = 0,25

increase is 1+0.25

M1 = 80.(1+0.25)¹ = 80.1.25 = 100

M10 = 80 (1+0.25)¹⁰ = 80. 9.313225 = 745.05 (end of the month)
