Just substitute 3 for m, and solve for b:
3.95*3 + 8.95b = 47.65
11.85 + 8.95b = 47.65

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.
