Answer:
18 Quarters
Explanation:
Question is a bit confusing and broad, but I think I understand it. It says that Alyssa gets 9 quarters from each car wash and that she did it for 7 days. If she does 2 car washes, then they should have made 18 quarters. This is because if she makes 9 quarters for each car wash, then for 2 car washes, she should make 18.
