McGilla Golf has decided to sell a new line of golf clubs. The clubs will sell for $830 per set and have a variable cost of $430 per set. The company has spent $153,000 for a marketing study that determined the company will sell 57,000 sets per year for seven years. The marketing study also determined that the company will lose sales of 9,800 sets of its high-priced clubs. The high-priced clubs sell at $1,130 and have variable costs of $730. The company will also increase sales of its cheap clubs by 11,300 sets. The cheap clubs sell for $470 and have variable costs of $245 per set. The fixed costs each year will be $9,130,000. The company has also spent $1,140,000 on research and development for the new clubs. The plant and equipment required will cost $28,910,000 and will be depreciated on a straight-line basis. The new clubs will also require an increase in net working capital of $1,330,000 that will be returned at the end of the project. The tax rate is 36 percent, and the cost of capital is 10 percent. Suppose you feel that the values are accurate to within only 10 percent. What are the best-case and worst-case NPVs? (Hint: The price and variable costs for the two existing sets of clubs are known with certainty; only the sales gained or lost are uncertain.) (Negative amounts should be indicated by a minus sign. Do not round intermediate calculations and round your final answers to 2 decimal places. (e.g., 32.16).)
