Answer
The percent increase is about 44%.
Solution
To find the percent increase, use the formula:
Percent Increase = [(New Value - Original Value) / Original Value] × 100
Substitute in the values:
Percent Increase = [(3.6 - 2.5) / 2.5] × 100
= (1.1 / 2.5) × 100
= 0.44 × 100
= 44%
The percent increase is about 44%.

To find the percent increase, you can use the formula: \[ \text{Percent Increase} = \left( \frac{\text{New Value} - \text{Old Value}}{\text{Old Value}} \right) \times 100 \] Substituting the numbers: \[ \text{Percent Increase} = \left( \frac{3.6 \text{ million} - 2.5 \text{ million}}{2.5 \text{ million}} \right) \times 100 = \left( \frac{1.1 \text{ million}}{2.5 \text{ million}} \right) \times 100 \approx 44.0\% \] The percent increase is about \( 44.0\% \).
