Mrs. Longchamp spent exactly $224 when she bought 28 more books for the library. She spent $96 on non -fiction books and $128 on fantasy books. The price of each non fiction was the same as the price of each fantasy book. How many of each did she buy?

Respuesta :

Mrs. Longchamp bought 12 non-fiction books and 16 fantasy books.

Given:
Total cost = 224
Total # of books = 28
cost of non-fiction = $96
cost of fantasy = $128

Each book has the same price. So,

$224/28 = $8 per book

Non-fiction books = $96/$8 = 12 books bought
Fantasy books = $128/$8 = 16 books bought.
