The percent change is the increase or decrease in the value of a quantity. If the new value is larger than the original value then it is a percent increase and if the change in value is lesser than the original value it is called percentage decrease.

Discount is a percentage of the original price that is subtracted from the price of the item the final price is called selling price. It is a percent of the decrease in the cost.

We are given the following price and the discount percentages:

Jeans: $24.50

discount: 33%

The discount is 33% of the price. We will subtract this amount from the original price.

So If x represents the new price after subtracting the discount then we have:

$\begin{array}{l}x=\text{Cost-Discount}\%\text{ofCost}\\ x=\$24.50−33\%×\$24.50\\ x=24.50−\frac{33}{100}×24.50\\ x=24.50−0.33×24.50\\ x=24.50−8.085\\ x=\$16.415\end{array}$

Thus, the discounted price of the jeans is $16.415.
