To determine the percent of change for the novel's price, we use the formula for percent change:
\[
\text{Percent Change} = \frac{\text{New Price} - \text{Old Price}}{\text{Old Price}} \times 100
\]
In this case, the old price is the regular price of $24.95, and the new price is the sale price of $14.97.
Now, plug in the numbers:
1. Calculate the difference in price:
\[
14.97 - 24.95 = -9.98
\]
2. Now, calculate the percent change:
\[
\text{Percent Change} = \frac{-9.98}{24.95} \times 100 \approx -40.05
\]
The negative sign indicates a decrease in price. So, the percent of change is approximately **40.05% decrease**.
\[
\text{Percent Change} = \frac{\text{New Price} - \text{Old Price}}{\text{Old Price}} \times 100
\]
In this case, the old price is the regular price of $24.95, and the new price is the sale price of $14.97.
Now, plug in the numbers:
1. Calculate the difference in price:
\[
14.97 - 24.95 = -9.98
\]
2. Now, calculate the percent change:
\[
\text{Percent Change} = \frac{-9.98}{24.95} \times 100 \approx -40.05
