B Correct answer
Explanation

If the price after a 20% discount is 10, then 0.8 * Original Price = 10. Original Price = 10 / 0.8 = 12.5.

AI explanation

Let the original selling price be P, which becomes P multiplied by 0.80 after a 20% markdown. Setting this equal to the sale price gives P times 0.80 equals 10, so P equals 10 divided by 0.80. This results in an original selling price of $12.5.
