1. The problem asks for the percent of change from 60 to 84. 2. The formula for percent change is: $$\text{Percent Change} = \frac{\text{New Value} - \text{Original Value}}{\text{Original Value}} \times 100\%$$ 3. Substitute the values into the formula: $$\frac{84 - 60}{60} \times 100\%$$ 4. Calculate the numerator: $$84 - 60 = 24$$ 5. So the expression becomes: $$\frac{24}{60} \times 100\%$$ 6. Simplify the fraction by canceling common factors: $$\frac{\cancel{24}}{\cancel{60}} = \frac{2}{5}$$ 7. Now multiply by 100%: $$\frac{2}{5} \times 100\% = 40\%$$ 8. Since the new value is greater than the original, this is a 40% increase. Final answer: **40% increase**
