A:
His deposits can be represented as 34.98, 51.02, and 51.22; his withdrawals would be -3.23, -4.22 and -9.79. In order from least to greatest, it would be -3.23, -4.22, -9.79, 34.98, 51.02, and 51.22. If he starts with $98, after all of the deposits and withdrawals he will have $217.98. Add all of the deposits and subtract all of the withdrawals.
