Ana, this is the solution to the problem:
• Price of the books = $ 1,137.50
,• Number of books = 350
,• Pricer per book = 1,137.50/350 = 3.25
,• Profit = $ 1,500
,• Profit per book = $ 4.29
In consequence, the price of sell of each book should be:
• Price of sell = Cost + Profit
,• Price of sell = 3.25 + 4.29
,• Price of sell = $ 7.54
