To calculate the percentage increase, we can use the formula:

\[
\text{Percentage Increase} = \frac{\text{New Price} - \text{Original Price}}{\text{Original Price}} \times 100
\]

For this problem:

- **Original Price** = $85
- **New Price** = $119

Substitute these values into the formula:

\[
\text{Percentage Increase} = \frac{119 - 85}{85} \times 100
\]

1. Calculate the difference: $ 119 - 85 = 34 $.
2. Divide by the original price: $ \frac{34}{85} \approx 0.4 $.
3. Convert to percentage: $ 0.4 \times 100 = 40\% $.

### Answer:
The percentage increase is **40%**.
