Answer:
Discounted payback period = 1.89 years
Explanation:
If Initial cost is $5,200
Year Cash flow Present value Present value Discounted
at 11% Cumulative cash flow
0 -5,200 1 -5,200 -5,200
1 2,800 0.9009 2,523 -2,677
2 3,700 0.811 3,003 326
3 5,100 0.73126 3,729 4,055
4 4,300 0.6587 2,833 6,887
Discounted payback period = 1 + (2,667/3003)
=1.89 years
