Answer:
3.53 years
Explanation:
The computation of the payback period is shown below:
In year 0 = $8,300
In year 1 = $2,100
In year 2 = $3,000
In year 3 = $2,300
In year 4 = $1,700
If we sum the first 3 year cash inflows than it would be $7,400
Now we subtract the $7,400 from the $8,300 , so the amount is $900 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 $1,700
So, the payback period equal to
= 3 years + $900 ÷ $1,700
= 3.53 years
