Answer

480
The regular price is 600andthediscountis20600 and the discount is 20%. To find the discount amount, multiply 600 by 0.20, which yields 120.Subtractingthe120. Subtracting the 120 discount from the regular 600priceresultsinafinalsalepriceof600 price results in a final sale price of 480.

Step-by-Step Solution

1
Calculate the amount of the discount.
20% of 600=0.20×600=600 = 0.20 \times 600 = 120
The discount is a percentage of the regular price.
2
Subtract the discount amount from the regular price to find the final sale price.
600−600 - 120 = $480
A discount reduces the original cost of the item.

Key Concept

Calculating the final price after a simple percentage discount is applied.

Alternative Method

Instead of calculating the discount and subtracting it, you can multiply the regular price by the percentage of the price you are actually paying. If the discount is 20%, you pay 100% - 20% = 80% of the original price. 600×0.80=600 \times 0.80 = 480.
