Answer:
2.22 years
Explanation:
For discounted payback period, find the PV of each year's cashflow;
Year PV of CF Net CF
0 -950 -950
1 525/1.1 = 477.2727 -472.7273
2 485/1.1² = 400.8264 -71.9009
3 445/ 1.1³ = 334.3351 262.4342
Discounted payback = last year with negative Net CF + (Absolute net CF that year/ PV of CF the following year)
= 2 +(71.9009/334.3351 )
= 2 + 0.215
= 2.22 years
