Let's say the cost of one book is "x" dollars.
According to the problem, the total cost of the two books is $65. So, the equation for the total cost is x + (x + 9) = 65.
Write the equations: Two of Julie’s textbooks are a total of $65. The difference in price between the two books is $9. What is the cost of each book
so what will the equation be for the difference in price between the two books?
