Explanation:

Step1: Calculate the amount of decrease

The original price is \( \$40 \) and the sale price is \( \$24 \). The amount of decrease is \( 40 - 24=\$16 \).

Step2: Use the percent - decrease formula

The percent - decrease formula is \( \text{Percent Decrease}=\frac{\text{Amount of Decrease}}{\text{Original Amount}}\times100\% \).
Substitute the values: \( \text{Percent Decrease}=\frac{16}{40}\times 100\% \).
First, simplify \( \frac{16}{40}=\frac{2}{5} \).
Then, \( \frac{2}{5}\times100\%=(2\times20)\% = 40\% \).

Answer:

A. \( 40\% \)
