Accepted Solution
A:
Evelyn has $524.96 in her checking account. She wrote a check for $32.50 today. She left only 524.96-32.50 And call amount of money she needs to deposit is x and she has now 524.96-32.50+x But She must maintain a $500 balance to avoid a fee, so we need: 524.96-32.50+x≥500 Solve: 492.46+x≥500 or x≥500-492.46 and x ≥ $7.54
And the answer is a) 524.96 − 32.50 + x ≥ 500; x ≥ $7.54
