its b(10-4)=450

Explanation:

Answer 2

Answer: There are 10 books in all.

Explanation:

Let x be the total number of books.

Since we have given that

Amount he paid for college textbooks = $450

Price of each book = $75

Number of books checked out for free = 4

So, Number of books which are not free would be

`(450)/(75)=6`

So, the total number of books would be

x = Number of books which are not free + Number of books which are free

`x=6+4=10`

Hence, there are 10 books in all.
