Answer:
3.36 years
Explanation:
The cash outflows and the cash inflows are shown below:
In year 0 = $4,300
In year 1 = $550
In year 2 = $970
In year 3 = $2,600
In year 4 = $500
When we add the first three-year cash inflows, it would be $4,120 Now we subtract the $4,120 from the $4,300, so the sum would be $180 as if we added the fourth-year cash inflow to the initial investment, then it exceeds.
Therefore, we subtract it, and the next year's cash inflow will be $500.
= 3 years + $180 ÷ $500
= 3.36 years
