a shirt went on sale for 18.00 if the shirt orignally cost 22.50, find was the percent decrease dut to the sale

Answer 1

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

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

In this case, the original price of the shirt is $22.50, and the sale price is $18.00.

1. First, calculate the decrease in price: \[ \text{Decrease} = \text{Original Price} - \text{Sale Price} = 22.50 - 18.00 = 4.50 \]

2. Next, plug the values into the percent decrease formula: \[ \text{Percent Decrease} = \left(\frac{4.50}{22.50}\right) \times 100 \]

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

4. Then multiply by 100 to get the percentage: \[ 0.2 \times 100 = 20% \]

So, the percent decrease in the price of the shirt due to the sale is 20%.
