Choose the best equation that fits the word problem below.

Question

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

A
15b = 60

B
60b = 15

C
15 + b = 60

D
15 + 60 = b

Answer 1

The best equation that fits the word problem is:

A. 15b = 60

This equation represents the total cost of the books (15 dollars per book times the number of books, \( b \)) being equal to the total amount of money Sarah has saved ($60).
