Question

Renee bought a book for $6.50 and some new notebooks for $2 each. She spent a total of $22.50. Write and solve an equation to determine the number of notebooks Renee bought.

Answer 1

In solving the provided linear equation to find out how many notebooks Renee bought, we subtract the cost of the book from the total cost and divide the result by the cost of each notebook. It turns out that Renee bought 8 notebooks.

Step-by-step explanation:

The subject of the question involves mathematics, specifically dealing with the creation and solving of a linear equation based on a given word problem. Renee spent a total of $22.50 on a book and several notebooks. The cost of the book was $6.50, and each notebook cost $2.00. We need to find out the number of notebooks she bought.

To determine the number of notebooks, we can set up the equation n for the number of notebooks. The total cost of the notebooks will be 2n (since each notebook costs $2). Renee's total expenditure was the cost of the book plus the cost of the notebooks, so we have the equation 6.50 + 2n = 22.50. To solve for n, we subtract the cost of the book from the total spending:

• 2n = 22.50 - 6.50
• 2n = 16.00
• n = 16.00 / 2
• n = 8

Therefore, Renee bought 8 notebooks.
