Eric has been donating books he no longer needs to his local library. After 3 months of donating, he had 157 books left in his room. After 8 months of donating, he had 102 books left in his room. How many books per month did Eric donate on average between months 3 and 8?

-31 books per month

-18 books per month

-11 books per month

-7 books per month

Answer 1

month 3 = 157 books
month 8 = 102 books
month 3 to month 8 = 5 months; books donated 157-102 =55 books
so, 5 months donated 55 books
for 1 month divide 5months by 5 keep balance so 55 books /5
11 books per month donated
