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.
