Understanding the Basics of Discounts

Discounts are a common way to reduce the original price of a product, making it more affordable for customers. To calculate the sale price of an item after a discount, we need to understand the original price, the percentage of the discount, and the sale price. In this article, we will explore how to calculate the sale price using a table.

The Table: Calculating Sale Prices

Original Price	Percent of Discount	Sale Price
$75	30%
$18	65%
	30%	$42
$35	55%

Calculating the Sale Price for Each Item

1. Original Price: $75, Percent of Discount: 30%

To calculate the sale price, we need to find 30% of the original price and subtract it from the original price.

Step 1: Find 30% of the original price. 30% of $75 = 0.30 x $75 = $22.50

Step 2: Subtract the discount from the original price. Sale Price = Original Price - Discount Sale Price = $75 - $22.50 Sale Price = $52.50

2. Original Price: $18, Percent of Discount: 65%

To calculate the sale price, we need to find 65% of the original price and subtract it from the original price.

Step 1: Find 65% of the original price. 65% of $18 = 0.65 x $18 = $11.70

Step 2: Subtract the discount from the original price. Sale Price = Original Price - Discount Sale Price = $18 - $11.70 Sale Price = $6.30

3. Original Price: $35, Percent of Discount: 55%

To calculate the sale price, we need to find 55% of the original price and subtract it from the original price.

Step 1: Find 55% of the original price. 55% of $35 = 0.55 x $35 = $19.25

Step 2: Subtract the discount from the original price. Sale Price = Original Price - Discount Sale Price = $35 - $19.25 Sale Price = $15.75

4. Percent of Discount: 30%, Sale Price: $42

To calculate the original price, we need to find the percentage of the sale price that is the discount.

Step 1: Find the percentage of the sale price that is the discount. Discount = (Sale Price / Original Price) x 100 30% = (42 / Original Price) x 100

Step 2: Solve for the original price. Original Price = (42 / 0.30) x 100 Original Price = $140

5. Original Price: $140, Percent of Discount: 30%

To calculate the sale price, we need to find 30% of the original price and subtract it from the original price.

Step 1: Find 30% of the original price. 30% of $140 = 0.30 x $140 = $42

Step 2: Subtract the discount from the original price. Sale Price = Original Price - Discount Sale Price = $140 - $42 Sale Price = $98
