Answer:
40 comic books
Explanation:
well i dont see a graph but i can give you x, the number of comic books he can buy!
so if he must have a minimum balance of $12 and right now he has $72 then we subtract those and see how much money he has to spend
so that gives us $60 to spend on the comic books
so if each comic book costs $1.50 then we divide that into the $60 leaving us with
40 comic books that jon can buy!
