Red Balloon purchases Graphic Novels for $7 each and wants to price them at $17.00 each. The store manager, Chaya, wants to make at least a 56% margin on the novels but she also wants to add a premium to the offer to add value for consumers without increasing the price. She can add bubblegum for $.50, a lollipop for $1, or a store branded bookmark for $1.50. What premium can Chaya add to the Graphic Novels and still make at least a 56% margin?
