Answer:
Option A
Step-by-step explanation:
The question asks how much did Sarah spend per book.
The statement in the problem that she $42.20 on 2 books would be enough information to solve the question given.
Using the information, we would find the unit rate of the price to get our answer.
Hope this helps.
