A new roller coaster just opened at Friday Fun Park. When Lisa got in line, a sign said the wait from that point would be 45 minutes. The actual wait was only 35 minutes. What is the percent error for the park sign's estimate? If necessary, round your answer to the nearest tenth of a percent.

To calculate the **percent error** for the park sign's estimate, use the following formula:

$$
\text{Percent Error} = \left( \frac{|\text{Estimated Value} - \text{Actual Value}|}{\text{Actual Value}} \right) \times 100\%
$$

Given:
- **Estimated wait time** = 45 minutes
- **Actual wait time** = 35 minutes

Plugging in the values:

$$
\text{Percent Error} = \left( \frac{|45\, \text{minutes} - 35\, \text{minutes}|}{35\, \text{minutes}} \right) \times 100\% = \left( \frac{10}{35} \right) \times 100\% \approx 28.571\%
$$

Rounding to the nearest tenth of a percent:

$$
\text{Percent Error} \approx 28.6\%
$$

**Answer:**  
The percent error in the estimate is 28.6 %.
The percent error in the estimate is 28.6%.
