The company will bring 1,000 ounces to the market next month. (a) What will be total revenues if the rm remains unhedged for gold prices of $600, $630, and $680 an ounce? (b) The futures price of gold for delivery one month ahead is $660. What will be the rm's total revenues at each gold price if the rm enters into a one month futures contract to deliver 1,000 ounces of gold? (c) What will total revenues be if the rm buys a one month put option to sell gold for $650 an ounce? The put option costs $45 per ounce.
