A used book store about $500 dollars worth of books they sold the books for $1,200 making $7.00 per book how many books were involved

Respuesta :

047
cost of books = $500
selling price = $ 1200

Profit = $1200 - $500 = $700
profit from each book = $7
Number of books = total profit/ profit per book = $700/$7 = 100

So there were 100 books.
