The number of books donated to a library is increasing by 25% each month. Initially, there were 80 books donated to the library.

Answer: There would be 745 books at the end of month 10.

Step-by-step explanation:

Since we have given that

Number of books initially = 80

Rate of growth = 25% = 0.25

t = 10 months

We need to find the number of books that are expected at the end of month 10.

As we know the formula for "Compound interest":

$A=P(1+\dfrac{r}{100})^t\\\\A=80(1+\dfrac{25}{100})^{10}\\\\A=80(1+0.25)^{10}\\\\A=80(1.25)^{10}\\\\A=745.05$

Hence, there would be 745 books at the end of month 10.
