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%.
