Answer:
People should disregard schooling and thus work in the entire life period.
Explanation:
Condition 1--- Work throughout the 4 periods
The NPV = 
= 27,272. 7 + 24,793.3 + 22,539.4 +20,490.4
= 95,095.8
Condition 2 - Attend school and work later
The NPV = -28,000 + 
= -28000 + 41,322.31 + 37,565.7 + 34,150.6
= 85,038.61
Conclusion: Since the NPV of not going to school is higher, people should disregard schooling. They should work in the entire life period.
Answer:
The required rate of return on stock is 14.6% and option b is the correct answer.
Explanation:
The required rate of return is the minimum return that investors demand/expect on a stock based on the systematic risk of the stock as given by the beta. The expected or required rate of return on a stock can be calculated using the CAPM equation.
The equation is,
r = rRF + Beta * (rM - rRF)
Where,
- rRF is the risk free rate
- rM is the return on market
r = 0.05 + 1.2 * (0.13 - 0.05)
r = 0.146 or 14.6%
