2. Zela is a manufacturer of clothing items. It costs them $3 to produce a t-shirt, which they sell to a wholesaler at a 50% margin. They know that the wholesaler then adds a 100% markup, and that the retailer takes a margin of 50%. Zela has now decided that rather than going through the wholesaler and the retailer, they will sell their t-shirts directly to the consumer. They plan to sell their t-shirts at the same price as the retailer. Based on this information: a. What is Zela's new margin in dollars and in percentage? b. What is the percentage change for Zela's margin (from their initial margin to the new margin)?
