Question

A.
2%

B.
20%

C.
45%

D.
80%

Answer 1

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

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

In this case:

• Original Price = $22.50
• Sale Price = $18.00

First, calculate the decrease in price:

\[ \text{Decrease in Price} = \text{Original Price} - \text{Sale Price} = 22.50 - 18.00 = 4.50 \]

Now, use the formula to find the percent decrease:

\[ \text{Percent Decrease} = \frac{4.50}{22.50} \times 100 \]

Calculating the fraction:

\[ \frac{4.50}{22.50} = 0.2 \]

Now, multiply by 100 to convert to percentage:

\[ 0.2 \times 100 = 20 \]

Thus, the percent decrease in price is 20%.

The correct answer is B. 20%.
