Choose the best equation that fits the word problem below.

Sarah is planning to buy some books. Each book (b) costs $15. How many books can Sarah purchase if she has saved $60?

1 answer

To find out how many books Sarah can purchase with her saved money, we can set up the following equation based on the information provided:

Let \( b \) be the number of books Sarah can buy. Each book costs $15, and Sarah has $60 saved. The equation that represents this scenario is:

\[ 15b = 60 \]

This equation shows that the total cost of the books (15 dollars per book multiplied by the number of books) is equal to the amount of money Sarah has saved ($60).

To solve for \( b \): \[ b = \frac{60}{15} \] \[ b = 4 \]

So, Sarah can purchase 4 books.
