Question 2.
Solution: For making determining the best investment opportunity we have calculate the present value of each alternative:
Present value of alternative (a) = $100,000 (given)
Present value of alt. (b) = $400,000 / (1.06)15 = 166,906.02
Present value of alt. (c) = 18,000 [1-(1.06)-10] / 0.06 = 132,481.57
Present value of alt. (d) = $75,000/ (1.06)5 + $100,000/(1.06)10 = 111,883.84
Present value of alt. (e) = $75,000 /(1.06)5+ $175,000 / (1.06)15 = $129,065.74
Since, Present value of the alternative (b). is higher than others thus, it is a best investment opportunity.
