To find the percentage of interest paid, you can use the formula:
\[ \text{Interest Rate} = \left( \frac{\text{Interest Paid}}{\text{Principal}} \right) \times 100 \]
In this case:
- Interest Paid = $29.61
- Principal = $987
Now, substituting the values into the formula:
\[ \text{Interest Rate} = \left( \frac{29.61}{987} \right) \times 100 \]
Calculating this gives:
\[ \text{Interest Rate} = \left( 0.02996 \right) \times 100 \approx 2.996% \]
So, the percentage of interest paid was approximately 3.00%.
