Question 7A: Keisha has $585.43 in her checking account. She must maintain a balance of $300 to avoid a fee. She wrote a check for $302.05 today. Write an inequality, using x for the variable, that would be used for the least amount of money she needs to deposit to avoid a fee.

585.43x - 302.05 ≥ 300
585.43 - 302.05 + x ≥ 300
585.43 - 302.05 + x ≤ 300
585.43x - 302.05 ≤ 300
