Justify your answer. 80% markup: Retail Price = Wholesale (100% + Markup Percent)Retail Price = x(100% +80%)Retail Price = x (180%)Retail Price = x(1.8) Retail Price = 1.8x 30% discount 1.8x (100% - 30%) 1.8x (70%) 1.8x(0.7) = 1.26x Situation 1 Final amount: 1.26x 30% markup: Retail Price = Wholesale (100% + Markup Percent)Retail Price = x(100% +30%)Retail Price = x (130%)Retail Price = x (1.3) Retail Price = 1.3x 80% discount 1.3x (100% - 80%) 1.3x (20%) 1.3x(0.2) = 0.26x Situation 2 Final amount: 0.26x Situation 1, the 80% markup followed by a 30% discount results in a greater final amount because you are increasing the price by a lot and reducing it by a little, whereas in situation 2, you are increasing the original price by a little and discounting it by a lot.
