13. From 1, 2 NPV = PV 3 – Cost of MBA = 71151.686 - 74,149.91 NPV = $(2,998.223) MBA

14. Financial Planning Advice  I will suggest Natasha as a Financial Planning to enroll in the Certificate Program based on her desire that she is not expect to lose any income during the certificate. Moreover, its impossible to implement this condition if she choose the MBA program unless she sell a fraction of her future earning from her treasury bond or she could barrow money from other recourses.
