Given :

To avoid a service fee, your checking account balance must be at least $400 at the end of each month.

Your current balance is $432.993.

You use your debit card to spend $119.86.

To Find :

What possible amounts can you deposit into your account by the end of the month to avoid paying the service fee.

Solution :

Amount left in the account :

A = $432.993 - $119.86

A = $313.133

Let, amount added is x.

So,

A + x ≥ 400

x + 313.133 ≥ 400

x ≥ 400 - 313.133

x ≥ 86.867

Therefore, possible amount needed is greater than or equal to $86.867 .

Hence, this is the required solution.
