To find the amount of interest you will owe, we need to calculate the interest using the formula:
Interest = Principal * Rate * Time
Where:
- Principal = $777 (the amount you owe)
- Rate = 18% per year (expressed as a decimal, or 0.18)
- Time = 1 year (since you have been making payments for a year)
Plugging in these values, we get:
Interest = $777 * 0.18 * 1
Interest = $139.86
So, the amount of interest you will owe is approximately $139.86.
