To calculate the percent change in Jess's hourly wages, we can use the following formula:

\[ \text{Percent Change} = \frac{\text{New Value} - \text{Old Value}}{\text{Old Value}} \times 100 \]

In this case, the new value (after the raise) is $9.85, and the old value (before the raise) is $8.50.

  1. Calculate the difference: \[ 9.85 - 8.50 = 1.35 \]

  2. Now, divide the difference by the old value: \[ \frac{1.35}{8.50} \approx 0.158823529 \]

  3. Finally, multiply by 100 to get the percentage: \[ 0.158823529 \times 100 \approx 15.88 \]

Now rounding to the nearest hundredth, we find the percent change is approximately 15.88%.

Therefore, the correct response is:

15.88%
