Answer:
6
Explanation:
first we do 90-11.65=78.35
then we need to find out how much money she can spend
so you do 78.35-56=22.35
so she can spend a total of 22.35 on her comic books
now you need to find out how much books she can buy with the 22.35 that she has
so the equation would be 22.35÷3.72=6
she can buy 6 comics total
