Answer:
3.52 years
Explanation:
In the payback, we analyze in how many years the invested amount is recovered. The computation is shown below:
In year 0 = $1,100
In year 1 = $300
In year 2 = $310
In year 3 = $320
In year 4 = $330
In year 5 = $340
If we sum the first 3 year cash inflows than it would be $930
Now we deduct the $930 from the $1,100 , so the amount would be $170 as if we added the fourth year cash inflow so the total amount exceed to the initial investment. So, we deduct it
And, the next year cash inflow is $320
So, the payback period equal to
= 3 years + ($170 ÷ $330)
= 3.52 years
In 3.52 years, the invested amount is recovered.
