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

1 answer

Let's say the cost of one textbook is x dollars.
The cost of the other textbook will be x + 9 dollars because the difference in price between the two books is 9 dollars.
The total cost of both textbooks is x + (x + 9) = 65 dollars.
Combining like terms, we get 2x + 9 = 65.
Subtracting 9 from both sides, we have 2x = 56.
Dividing both sides by 2, we find x = 28.
Thus, each book costs $28, and the more expensive textbook costs $28 + $9 = $<<28+9=37>>37. Answer: \boxed{37}.
