Baird Golf has decided to sell a new line of golf clubs. The clubs will sell for $$815$ per set and have a variable cost of $$435$ per set. The company has spent $$160,000$ for a marketing study that determined the company will sell $85,000$ sets per year for seven years. The marketing study also determined that the company will lose sales of $20,000$ sets of its high$-$priced clubs. The high$-$priced clubs sell at $$1,250$ and have variable costs of $$670.$ The company will also increase sales of its cheap clubs by $22,000$ sets. The cheap clubs sell for $$525$ and have variable costs of $$245$ per set. The fixed costs each year will be $$9,500,000.$ The company has also spent $$1,100,000$ on research and development for the new clubs. The plant and equipment required will cost $$30,800,000$ and will be depreciated on a straight$-$line basis. The new clubs will also require an increase in net working capital of $$1,500,000$ that will be returned at the end of the project. The tax rate is $40\%,$ and the cost of capital is $10\%.$
