The company has spent $320,000 for a marketing study thatdetermined the company will sell 70,000 sets per year for sevenyears. The marketing study also determined that the company willlose sales of 13,400 sets of its high-priced clubs. The high-pricedclubs sell at $1,225 and have variable costs of $685. The companywill also increase sales of its cheap clubs by 15,400 sets. Thecheap clubs sell for $445 and have variable costs of $235 per set.The fixed costs each year will be $10,650,000. The company has alsospent $2,700,000 on research and development for the new clubs. Theplant and equipment required will cost $39,000,000 and will bedepreciated on a straight-line basis. The new clubs will alsorequire an increase in net working capital of $3,400,000 that willbe returned at the end of the project. The tax rate is 22 percent,and the cost of capital is 10 percent.
