To find the equivalent annual interest rate for the payday loan, we can use the formula for the interest rate over a given period. The simple interest formula is: \[ \text{Interest Rate} = \left( \frac{\text{Interest}}{\text{Principal}} \right) \times \left( \frac{365}{\text{Number of Days}} \right) \] In this case, the interest is the fee of \( \$ 50 \), the principal is \( \$ 500 \), and the number of days is \( 11 \): \[ \text{Interest Rate} = \left( \frac{50}{500} \right) \times \left( \frac{365}{11} \right) \] Calculating this, we get: \[ \text{Interest Rate} = 0.1 \times 33.18 \approx 3.318 \] To express this as a percentage, we multiply by \( 100 \): \[ \text{Interest Rate} \approx 331.8\% \] Rounding to the nearest percent, the equivalent annual interest rate is \( 332\% \).
