Answer:
$340.00.
Explanation:
If William's current monthly expenses are $2,660.00 and he earns $3,000.00 each month, then his disposable income (income minus expenses) is:
$3,000.00 - $2,660.00 = $340.00
This means that William can afford to pay up to $340.00 extra on his car note this month. Therefore, the correct answer is $340.00.
