Hugh bought some magazines that cost $3.95 each and some books that cost $8.95 each. he spent a total of $47.65. let m represent the number of magazines and b represent the number of books. which equation models the situation?

m + b = 47.95

m + b = 60.55

3.95m + 8.95b = 47.65

8.95m + 3.95b = 47.65
