Multiple Choice Question
A shirt went on sale for $18.00. If the shirt originally cost $22.50, find was the percent decrease in price due to the sale.

Answer 1

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

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

In this case, the original price is $22.50 and the sale price is $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, substitute the values into the percent decrease formula:

\[
\text{Percent Decrease} = \left( \frac{4.50}{22.50} \right) \times 100
\]

Calculating the fraction:

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

Now, multiply by 100 to find the percent:

\[
0.2 \times 100 = 20
\]

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