Find the discounted price of each item.

guitar: $95.00

discount: 15%

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.

Sales tax is a percentage of the original cost which is added before selling an item. The final price is called the selling price. Similarly percentage discount is the cost that is reduced from the original price.

If we let the total cost of a computer game be x, and the original price is $95, is given.

x can be calculated as:

$$\begin{gathered} x=\text{Cost-Discount}\%\text{ofCost} \\ \begin{array}{l}x=\$95.00-15\%\times \$95.00\\ x=95.00-\frac{15}{100}\times 95.00\\ x=95.00-0.15\times 95.00\\ x=95.00-14.25\\ x=\$80.75\end{array} \end{gathered}$$

Thus, the discounted price of the guitar is $80.75.
