Question

At least one of these answers are wrong (probably more). Please help me get the right answer with the correct rounding! Thank you.

McGilla Golf has decided to sell a new line of golf clubs. The clubs will sell for $840 per set and have a variable cost of $440 per set. The company has spent $154,000 for a marketing study that determined the company will sell 58,000 sets per year for seven years. The marketing study a company will lose sales of 9,900 sets of its high-priced clubs. The high-priced clubs sell at $1,140 and have variable costs of $740. The company will also increase sales of its cheap clubs by 11,400 sets. The cheap clubs sell for $480 and have variable costs of $250 per set. The fixed costs each year will be $9,140,000. The company has also spent $1,150,000 on research and development for the new clubs. The equipment required will cost $28,980,000 and will be depreciated on a straight-line basis. The new clubs will also require an increase in net working capital of $1,340,000 that will be returned at the end of the project. The tax rate is 38 percent, and the cost of capital is 10 percent. Calculate the payback period. (Do not round intermediate calculations. Round your answer to 3 decimal places, e.g., 32.161.) Payback period 2.3 years Calculate the NPV. (Do not round intermediate calculations. Round your answer to 2 decimal places, e.g., 32.16.) NPV $ 60596024 Calculate the IRR. (Do not round intermediate calculations. Enter your answer as a percent rounded to 2 decimal places, e.g., 32.16.) IRR 6.10 %

Answer 1

1.
=(28980000+1340000)/((58000*(840-440)-9900*(1140-740)+11400*(480-250)-9140000-28980000/7)*(1-38%)+28980000/7)=3.20478942673166

2.
=-28980000-1340000+1340000/1.1^7+((58000*(840-440)-9900*(1140-740)+11400*(480-250)-9140000-28980000/7)*(1-38%)+28980000/7)/10%*(1-1/1.1^7)=16426963.3656112

3.
=RATE(7,((58000*(840-440)-9900*(1140-740)+11400*(480-250)-9140000-28980000/7)*(1-38%)+28980000/7),-28980000-1340000,1340000)=24.8287247775495%
