Explanation: In order to find the sale price of the dress, we first need to find the discount. The formula for discount is shown below.
Original Price × Rate of Discount = Discount
So here, the original price is $78 and the
rate of discount is 25% off or .25.
So we multiply (78)(.25) to get 19.50 so the discount is $19.50.
Now we can find the sale price.
The formula for sale price is shown below.
Original Price - Discount = Sale Price
So here, the original price is $78 and the discount is $19.50.
So subtracting 78 - 19.50, we get 58.50.
So the sale price is $58.50.
