McGilla Golf has decided to sell a new line of golf clubs. The clubs will sell for $$815$ per set and have a variable cost of $$365$ per set. The company has spent $$150,000$ for a marketing study that determined the company will sell $55,000$ sets per year for seven years. The marketing study also determined that the company will lose sales of $10,000$ sets of its high$-$priced clubs. The high$-$priced clubs sell at $$1,345$ and have variable costs of $$730.$ The company will also increase sales of its cheap clubs by $12,000$ sets. The cheap clubs sell for $$445$ and have variable costs of $$210$ per set. The fixed costs each year will be $$9\mathrm{.}45$ million. The company has also spent $$1$ million on research and development for the new clubs. The plant and equipment required will cost $$39\mathrm{.}2$ million and will be depreciated on a straight$-$line basis. The new clubs will also require an increase in net working capital of $$1\mathrm{.}85$ million that will be returned at the end of the project. The tax rate is $25$ percent, and the cost of capital is $10$ percent.

Suppose you feel that the values are accurate to within only $\backslash$pm $10$ 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.$)($A negative answer should be indicated by a minus sign.
