So Colin is required to pay $300 for 15 total months in order to get his credit card balance down to $0.
In order to find this total, we need to take the amount he is going to pay per month ($300) and multiply is by the total number of months that he is going to be paying that amount (15):
$300 * 15 months = $4,500
The total amount of money that he is going to pay after his card balance reaches $0 is $4,500.
However, Colin only maxed out his credit card to $4,000 - the rest of the money is due to interest. So to find this amount, we take the total amount that he paid ($4,500) and subtract it from the total amount he initially maxed out his card with ($4,000):
$4,500 - $4,000 = $500
The amount of interest that Colin has paid when his credit card balance is $0 is $500.
