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

The answer is 4 books

Answer 2

so first you want to find the price of all the magazines he bought which is 3.95 x 3 = 11.85.
then you are going to find out how much money he had left to spend on books which is 47.65-11.85=35.80

then you want to find how many books he bought with that money so you would take 35.80/8.95= 4

so he bought 4 books
