You have accumulated $55,000 in a mutual fund account that pays 10% interest. You are offered the opportunity to buy 220 ounces of gold at $250 per ounce. The price of gold is expected to rise to $650 per ounce by the end of five years. You realize, however, that this is only an estimate.

To what price would gold have to rise in order to earn a 10% return? (Note that the future value factor for $55,000 at 10% at the end of five years is l.6105.)
