Answer:
b. She should develop herself as the EMV of developing is $1.125 million, which is higher than the EMV of selling.
Explanation:
The probability of discovered oil = 0.25 (25%)
Selling the exploration right= Selling Price + Probability of discovered oil × Royalty% × Future Profit
= $200,000 + 0.25 × 0.25 × $7,500,000 = $668,750
Developing = Probability of finding the oil × Future Profits - Cost of Well
= 0.25 × $7,500,000 - $750,000 = $1,125,000
= $1.125 million
Therefore the EMV for selling the exploration rights is less than the developing, the landowner will develop the site by his own.

Explanation:
Answer: 26.73%
Explanation:
You can calculate the expected return using the Capital Asset Pricing Model (CAPM).
Formula is:
Expected return = Risk free rate + beta * (Market return - risk free rate)
Use the previous figures to solve for the risk free rate:
20.47% = Rf + 1.39 * (16.50% - Rf)
20.47% = Rf + 22.935% - 1.39R
20.47% - 22.935% = Rf - 1.39Rf
-2.465% = -0.39Rf
Rf = -2.465% / -0.39
= 6.32%
New expected return is:
= 6.32% + 1.39 * (21% - 6.32%)
= 26.73%
