A farmer wants to hedge the selling price. The farmer acts at planting time using the December futures price. When considering the hedge, the farmer sees that cash corn price is $4.70 and the December futures price is $4.40. The farmer sells a December contract at $4.40. Later, after harvest, the farmer sells corn in the cash market at $3.70 and buys a December future at $4.00 to offset the earlier sale of that future. Calculate the net selling price.
