Final answer:
The calculated NPV of Sarah Palin's book deal exceeds all provided options when factoring the royalties expected in perpetuity and the opportunity cost of foregone earnings from media appearances. Thus, it appears there is an error in the question as none of the given choices match the calculated result.
Step-by-step explanation:
To calculate the net present value (NPV) of Sarah Palin's book deal, we need to compare the cash inflows from royalties with her opportunity costs and adjust for the time value of money. The opportunity cost here is the $8 million she could have earned from speeches and TV appearances during the year she wrote the book. The royalties are expected to be $5 million at the end of the first year with a 40% decrease each year into perpetuity.
The cash flows from the royalties form a perpetuity where the present value can be calculated using the formula Present Value of a Perpetuity = Cash Flow / Discount Rate. Given that royalties decrease by 40% each year, we adjust the discount rate to reflect the decline. The adjusted discount rate is 10% - 40% of 10% (which is 4%), resulting in 6%.
Therefore, the present value of her royalties is $5 million / 0.06 = $83.33 million. The NPV of the book deal is then calculated as:
- NPV = Present Value of royalties - Opportunity Cost
- NPV = $83.33 million - $8 million
- NPV = $75.33 million
However, Sarah Palin received an $11 million advance, so the NPV after considering the advance is:
- NPV = $75.33 million - $11 million
- NPV = $64.33 million
Since the possible answers are all lower than $64.33 million, and we've considered only the most relevant costs and incomes, it's clear that there is likely an error in either the numbers provided or in the construction of the question, as the NPV calculated exceeds all given options. Therefore, no provided answer (A, B, C, or D) matches our calculated NPV based on the information provided.
