Gwen is buying 3 identical pairs of shoes that have a total cost of $40.50 after the discount of 40 percent off. What is the regular price of each pair?
Let's say p is the principal cost of the total (original) we can setup the equation p-.4p=40.5 => .6p=40.5 => p=67.5 So the cost without the sale is $67.50 For the original price of each pair divide this by 3. 67.5/3=22.5 Final answer: Each pair costs $22.50 without the sale. Hope I helped :)
