Answer

The discount of the sale price is $20 %$ .

1Step 1. State the concept of discount percent.

When the price of an article is reduced and sold it means a discount has been offered. When the price reduced is expressed as a percentage, it is called a discount percentage or the discount rate.

2Step 2. Calculate the amount discounted.

Actual price of the inkjet is $$ 179.00$ .

Selling price of the inkjet on the sale is $$ 143.20$ .

$\begin{array}{r} Discounted Amount=Actual price-Selling price \\ =179.00-143.20 \\ =$35.80 \end{array}$

The amount discounted is $$ 35.80$ .

3Step 3. Calculate the percent discount.

The percent discount is calculated as follows:

$% discount = \frac{Discounted Amount}{Actual price} \times 100 \dots (1)$

Substitute discounted amount as $35.80$ and actual price as 179 in equation (1) to get the percent discount.

$\begin{matrix} % discount= \frac{35.80}{179} \times 100 \\ = \frac{3580}{179} \\ = 20 \end{matrix}$

Therefore, the discount of the sale price is $20 %$ .
