Delon’s Department Store sells several of its own brands of clothes and several well-known designer brands as well. Delon’s is considering building a plant in Malaysia to produce silk ties. The plant will cost the firm $5.5 million. The plant will be able to produce the ties for $1.20 each. On the other hand, Delon’s can subcontract to have the ties produced and pay $3.00 each. How many ties will Delon’s have to sell worldwide to break even on its investment in the new plant?
