Problem 11 - Taxes
Target purchased 100 shirts from an international manufacturer for $18 each per list price. The manufacturer sold the shirts at a 10 % percent discount, FOB destination. The duty on the purchase was 25% percent ad valorem and $3 specific. The shirts will be sold at a markup of 40% percent on cost. A 3% percent sales tax will be added to the selling price. What is the amount that a customer will pay for one shirt?
