Question

Hugh bought some magazines that cost $3.95 each and some books that cost $8.95 each. He spent a total of $47.65. If Hugh bought 3 magazines, how many books did he buy?

The equation that models the problem is 3.95m + 8.95b = 47.65, where m is the number of magazines and b is the number of books.

Answer 1

4 BOOKS

Explanation:

Answer 2

4 books.

Explanation:

We have been that Hugh bought some magazines that cost $3.95 each and some books that cost $8.95 each. He spent a total of $47.65.

The equation
`3.95m+8.95b=47.85` represents the given problem.

To find the number of books, b, bought by Hugh, we will substitute
`m=3` in our given equation.

`3.95(3)+8.95b=47.65`

`11.85+8.95b=47.65`

`11.85-11.85+8.95b=47.65-11.85`

`8.95b=35.8`

`(8.95b)/(8.95)=(35.8)/(8.95)`

`b=4`

Therefore, Hugh can buy 4 books.
