Question

Help on inequalities please! :)

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 and solve an inequality to solve for the least amount of money he needs to deposit to avoid a fee.

638.54 + 159.50 − x ≥ 500; x ≥ $298.04

638.54 + 159.50 − x ≤ 500; x ≤ $298.04

638.54 − 159.50 + x ≥ 500; x ≥ $20.96

638.54 − 159.50 + x ≤ 500; x ≤ $20.96

Answer 2

He initially has $638.54 in his account, then he writes a check so that's minus $159.50. He needs to add a certain amount (x) to keep the balance above $500.
Writing all this mathematically : 638.54 − 159.50 + x ≥ 500
