Final answer:
To find the selling price of the outfit, you need to calculate the markup on each item and add it to the cost price. The selling price of the outfit is 70.4.
Step-by-step explanation:
To find the selling price of the outfit, we need to calculate the markup on each item and add it to the cost price. Given that the cost of the jacket is 34, the t-shirt is 9, and the shorts are 12, we calculate the markup on each item by multiplying the cost by the percentage of markup, which is 28% or 0.28.
Markup on the jacket = 34 * 0.28 = 9.52 Markup on the t-shirt = 9 * 0.28 = 2.52 Markup on the shorts = 12 * 0.28 = 3.36
Adding up the cost price and markup of each item, we get the selling price of the outfit: Selling price of the outfit = Cost of jacket + Markup on jacket + Cost of t-shirt + Markup on t-shirt + Cost of shorts + Markup on shorts = 34 + 9.52 + 9 + 2.52 + 12 + 3.36 = 70.4
