Answer:
6.89 years
Step-by-step explanation:
The discounted payback period can be calculated by using the following table
Year Cash flows PV(13%) Cumulative Cash flows
0 (70000) (70000) (70000)
1 16000 14159.29 (55840.71)
2 16000 12530.35 (43310.36)
3 16000 11088.80 (32221.56)
4 16000 9813.10 (22408.46)
5 16000 8684.16 (13724.30)
6 16000 7685.10 (6039.20)
7 16000 6800.97 761.77
8 16000 6018.56 6780.33
Discounted Payback = 6 years + 6039/ 6801
Discounted Payback = 6.89 years
