You can put this solution on YOUR website! To solve, we must set this word problem up as an equation. To do this, we need to first know the formula for finding the original price after a % mark down. This formula is
Original Price - (% markdown in decimal form)(Original Price) = Discounted Price
Since we do not know the original price, we will represent it by the letter x. Now, let's replace the information in the formula for the information we know:
Original Price: x
% Markdown in decimal form: .085
Discounted Price: $484.95
x - .085x = 484.85
Combine like terms on the left, which gives us
.915x = 484.85
Finally, divide both sides of the equation by .915 to obtain x:
x = 484.85/.915 ------> x = 530
Original Price = $530.00
