Final answer:
The original selling price of the ski set is $400 because of the markdowns applied. Option A is correct.
Step-by-step explanation:
The original selling price is the price at which a product or service was first offered for sale. It is the price that the seller was initially asking for the item, before any discounts or markdowns were applied. The original selling price is often used as a reference point for determining the current price of an item, as well as for calculating discounts and markdowns.
To find the original selling price of the ski set, you can work backwards from the sale price after the markdowns.
Let the original selling price be x.
The markdowns are applied successively, so the calculation would look like this:
Original price - 20% = $321
x - 0.20x = $321
0.80x = $321
x = $321 / 0.80
x = $401.25
The original selling price of the ski set was $401.25, which is closest to option A) $400.
