Louisa paid $12.25 for books at a yard sale. She spent $2.50 on a hardcover book, ad the rest on 13 softcover books. Each of the softcover books. Each of the softcover books at the same time. What was the cost of a singe softcover book?

First you must find the total cost spent without the hard cover book

12.25-2.50 = 9.73

You must divide 13 into 9.75 

9.75/13

leaving you with .75cents as your total cost per soft covered book

Thanks
