On June 30, the manager of the oil companys refinery (located in Chicago) notes that the spot price of Chicago gasoline is $2.00 per gallon. At the same time, the price of August gasoline futures contracts is $1.97 per gallon. The manager anticipates selling 4.2 million gallons of gasoline in the Chicago area during July, and sells 100 gasoline futures contracts at $1.97 on June 30 to hedge its gasoline price exposure. (NOTE: each gasoline futures contract calls for delivery of 42,000 gallons of gasoline in New York Harbor). Answer the following:
