15% off an item purchased at $30 is equal to $4.50, so $4.50 is the 15% discount and you will pay $25.50.
How to work out discounts - Step by Step:
To calculate percent off use the following equations:
- Amount Saved = Original Price x Discount % / 100
- Sale Price = Original Price - Amount Saved
1.) What is 15 percent (%) off $30?
Using the formula 1 and replacing the given values:
Amount Saved = Original Price x Discount % / 100. So,
Amount Saved = 30 x 15 / 100
Amount Saved = 450 / 100
Amount Saved = $4.5 (answer)
In other words, a 15% discount for an item with original price of $30 is equal to $4.5 (Amount Saved).
Note: To find the amount saved, just multiply it by the percentage and divide by 100.
2.) How much to pay for an item of $30 when discounted 15 percent (%)? What is item's sale price?
Using formula 2 and replacing the given values:
Sale Price = Original Price - Amount Saved. So,
Sale Price = 30 - 4.5
Sale Price = $25.50 (answer)
This means, the cost of the item to you is $25.50. You will pay $25.5 for an item with original price of $30 when discounted 15%.
