Answer and Explanation:
1A. For investment X, given 6% discount rate, 6700 PMT, N= 9 years
Present value of investment X= 6700* PVIF using 6%, 9 years
= $45751.34
For investment Y, given 6% discount rate, 9200 PMT, N= 5 years
Present value of investment Y =9200*PVIF using 6%, 9 years
=$38753.75
1B. Investment X from the above has higher present value
2A. For investment X, given 22% discount rate, 6700 PMT, N = 9 years
Present value of investment X
=6700*PVIF using 22% ,9 years
= $25368.11
For investment Y, given 22% discount rate, 9200 PMT, N = 5 years
Present value of investment X
=9200*PVIF using 22% ,N = 5 years
= $26345.49
2B. Investment Y from the above has higher present value.
