The answer depends on how the discount is defined. Discounts can be 10 currency units (dollars, pennies, whatever) off, or 10% off.
Original price = Sale price + Discount amount
Suppose percent discount is D. Then Marked Price = Sale Price/(1-D/100)
The discount is 15% of 45 = 45*15/100 = 6.75 The sale price is 45 - 6.75 = 38.25.
To calculate the sale price of the television after a 30% discount, you first need to find the amount of the discount. 30% of $459 is $137.70. Subtract this discount from the original price to find the sale price: $459 - $137.70 = $321.30. Therefore, the sale price of the television after the 30% discount is $321.30.
Discount = Original Price - Discounted Price Percentage Discount = 100* Discount / Original Price
