Answer:
It is not economically rational for Daniel to enroll in the course
Step-by-step explanation:
Increase in income = $23,000 - $18,000 = $5,000
i = 10% = 0.1
NPV = -(18,000 + 1,000) + 5,000/(1.1)^1 + 5,000/(1.1)^2 + 5,000/(1.1)^3
NPV = -17,000 + (4545.45 + 4132.22 + 3756.74)
NPV = -17,000 + 12,434.41
NPV = -4,565.59
Conclusion: Since NPV is Negative. Therefore, it is not economically rational. So the answer is NO.
