Brad had $530.45 in his checking account. He wrote checks for $16.50 and $95.68. He also made a deposit of $19.13. What is the approximate final balance in his account?

437.40

Step-by-step explanation:

a check would be a decrease to his checking account balance so 530.45 minus 16.50 would equal 513.95. 513.95 minus 95.68 equals 418.27. a deposit would be a increase to his balance. 418.27 plus 19.13 would equal 437.40.
