Question

Evelyn has $524.96 in her checking account. She must maintain a $500 balance to avoid a fee. She wrote a check for $32.50 today. Write and solve an inequality to solve for the least amount of money she needs to deposit to avoid a fee.

Answer 1

Let the amount she deposits be x, then the least amount of money she needs to deposit to avoid a fee is given by the inequality:
$524.96 - $32.50 + x >= $500
$492.46 + x >= $500
x >= $500 - $492.46
x >= $7.54
