Malcolm has $638.54 in his checking account. He must maintain a $500 balance to avoid a fee. He wrote a check for $159.50 today. Write an inequality that would be used to solve for the least amount of money he needs to deposit to avoid a fee. 638.54 +159.50 − x ≥ 500
638.54 + 159.50 − x ≤ 500
638.54 − 159.50 + x ≥ 500
638.54 − 159.50 + x ≤ 500
