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

Hugh bought 4 books.

If he bought 3 magazines, he spent 11.85 on magazines. If you subtract this from the total 47.65, you are left with 35.80. If you divide 35.80 by 8.95, you will get that he bought 4 books.
