Find the missing quantities by first computing the markup on one base and then computing the markup on the other. Round rates to the nearest tenth of a percent and dollar amounts to the nearest cent.
A. Markup = $2.12 Selling price = $3.47 % Markup on cost = 37.9% B. Markup = $3.43 Selling price = $9.02 % Markup on cost = 61.3% C. Markup = $3.43 Selling price = $2.16 % Markup on cost = 61.3% D. Markup = $2.12 Selling price = $7.71 % Markup on cost = 27.5%
