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?

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.

The answer for this question is 80

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post
