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 $770 per set and have a variable cost of $370 per set. The company has spent $147,000 for a marketing study that determined the company will sell 59,000 sets per year for seven years. The marketing study also determined that the company will lose sales of 9,200 sets of its high-priced clubs. The high-priced clubs sell at $1,070 and have variable costs of $670. The company will also increase sales of its cheap clubs by 10,700 sets. The cheap clubs sell for $410 and have variable costs of $215 per set. The fixed costs each year will be $9,070,000. The company has also spent $1,080,000 on research and development for the new clubs. The plant and equipment required will cost $28,490,000 and will be depreciated on a straight-line basis. The new clubs will also require an increase in net working capital of $1,270,000 that will be returned at the end of the project. The tax rate is 38 percent, and the cost of capital is 12 percent. What is the sensitivity of the NPV to each of these variables?
