Answer:
D) Mario owes the bank a little less than $50.
Explanation:
We know that Mario's bank account has a balance of -49.25 dollars.
The negative sign means that Mario doesn't have any money, in fact, he owes to the bank $49.25, that's what means the minus sign.
Basically, we could say that Mario owed the bank a little less than $50, because $49.25 < $50.
Therefore, the right answer is D.
