Answer: $21 left in her checking account
Explanation: She has $-11 in her account already then she gets $44.50 so you would do $-11 + $44.50= $33.50, then you would multiply $6.25 by 2 because she took her friend with her so that means 2 tickets, that would mean $6.25 * 2 that would get you $12.50 then you would subtract $33.50 from $12.50 to get your answer of $21
