Answer 1

To find the percent decrease in price, we can use the formula:

\[
\text{Percent Decrease} = \left( \frac{\text{Original Price} - \text{Sale Price}}{\text{Original Price}} \right) \times 100
\]

1. **Find the original price and the sale price**:
- Original Price = $22.50
- Sale Price = $18.00

2. **Calculate the decrease in price**:
\[
\text{Decrease} = \text{Original Price} - \text{Sale Price} = 22.50 - 18.00 = 4.50
\]

3. **Substitute the values into the percent decrease formula**:
\[
\text{Percent Decrease} = \left( \frac{4.50}{22.50} \right) \times 100
\]

4. **Calculate the fraction**:
\[
\frac{4.50}{22.50} = 0.2
\]

5. **Convert this to a percentage**:
\[
0.2 \times 100 = 20\%
\]

Thus, the percent decrease in price due to the sale is **20%**.

The answer is **B. 20%**.
