Marvin wrote a check of $58.25 for the water bill and $450 for rent. he also made a deposit of $124.16. how much is his new balance after writing the checks and making the deposit?

Assuming he has $0 in his bank account.

He deposits $124.16 into his account.

0 + 124.16 = 124.16

He then withdraws 58.25 & 450 for bill & rent.

58.25 + 450 = 508.25

Subtract.

124.16 - 508.25 = -384.09

-384.09 is his balance.
