McGilla Golf is evaluating a new line of golf clubs. The clubs will sell for $$910$ per set and

have a variable cost of $$405$ per set. The company has spent $$135,000$ for a marketing

study that determined the company will sell $46,000$ sets per year for seven years. The

marketing study also determined that the company will lose sales of $8,600$ sets of its

high$-$priced clubs. The high$-$priced clubs sell at $$1,410$ and have variable costs of $$540.$

The company also will increase sales of its cheap clubs by $11,200$ sets. The cheap clubs

sell for $$405$ and have variable costs of $$135$ per set. The fixed costs each year will be

$$9,200,000.$ The company has also spent $$950,000$ on research and development for

the new clubs. The plant and equipment required will cost $$28,000,000$ and will be

depreciated on a straight$-$line basis to a zero salvage value. The new clubs will also

require an increase in net working capital of $$2,260,000$ that will be returned at the end

of the project. The tax rate is $23$ percent, and the cost of capital is $14$ percent.
