Alice starts off with $650. Next she puts $300 into the bank. This gives us $950. Theeenn she takes out $120 which leaves us with $830. She transfers $125 to her checking which takes away $125. This means 830 - 125 which is 680 or $680. The writes checks for $43 and $28 which mean she looses $43 and $28. Minus the $43 would be $637 and minus the $28 would be $609. At the end of the month Alice has a balance of $609.
