Answer:
He bought 17 books.
Step-by-step explanation:
Given that:
Total money spent = $89
Cost of each book = $5
Shipping price = $4
We have to find, Total number of books
So if the number of books be represented by b, the equation will become:
Cost of one book * total number of books + shipping price = total money
Putting values we get:
5*b + 4 = $89
By simplifying:
5*b = 89 - 4
5*b = 85
Dividing both sides by 5 we get:
b = 17
So the total number of books bought is 17.
i hope it will help you!
