Answer:
$119.25.
Explanation:
Let's call the deposit amount "D".
Starting balance: $654.98
Check amount: -$321.45
Deposit: +D
Ending balance: $452.78
So, we can set up an equation:
$654.98 - $321.45 + D = $452.78
Solving for D:
$654.98 - $321.45 + D = $452.78
$333.53 + D = $452.78
D = $119.25
So the deposit amount was $119.25.
