7. Hedging with Futures versus Puts. A gold-mining firm is concerned about short-term volatil- ity in its revenues. Gold currently sells for $860 an ounce, but the price is volatile and could fall as low as $800 or rise as high as $920 in the next month. The company will bring 1,000 ounces to the market next month. (LO2)

a. What will be total revenues if the firm remains unhedged for gold prices of $800, $860, and $920 an ounce?

b. The futures price of gold for 1-month-ahead delivery is $880. What will be the firm's total revenues at each gold price if the firm enters a 1-month futures contract to deliver 1,000 ounces of gold?

c. What will total revenues be if the firm buys a 1-month put option to sell gold for $860 an ounce? The puts cost $6 per ounce.
