McGilla Golf has decided to sell a new line of golf clubs. The company would like to know the sensitivity of NPV to changes in the price of the new clubs and the quantity of new clubs sold. The clubs will sell for $825 per set and have a variable cost of $385 per set. The company has spent $260,000 for a marketing study that determined the company will sell 68,200 sets per year for seven years. The marketing study also determined that the company will lose sales of 12,200 sets of its high-priced clubs. The high-priced clubs sell at $1,195 and have variable costs of $655. The company will also increase sales of its cheap clubs by 14,200 sets
