A trader wants to form a position by combining two different European calls and two different European puts. The calls have the same expiration dates but have different strike prices. The trader sells one call with strike price of 48 at a price of 1.50, and buys one call with strike price of 50 at 1.00. He buys one put at a strike price of 48 at 0.50 and sells one put at a strike price of 50 at 2.50. Demonstrate how to graph the profits from this spread strategy by first producing a profits table, and then sketching the graph.
