Original cost of a pair of shoes = $40 Percentage by which the price of the pair of shoes is marked up = 25% Then Amount by which the price of the pair of shoes is marked up = (25/100) * 40 dollars = 40/4 dollars = 10 dollars So The selling price of the shoe now = (40 + 10) dollars = 50 dollars So we can see from the above deduction that the price of the pair of shoes was marked up by $10 and the selling price of the pair of shoes is $50. I hope the procedure is clear enough for you to understand.
