Answer:
A. 3.21 years
Explanation:
In the payback, we analyze in how many years the invested amount is recovered. The computation is shown below:
In year 0 = $7,500
In year 1 = $1,100
In year 2 = $1,640
In year 3 = $3,800
In year 4 = $4,500
If we sum the first 3 year cash inflows than it would be $6,540
Now we deduct the $6,540 from the $7,500 , so the amount would be $960 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 $4,500
So, the payback period equal to
= 3 years + $960 ÷ $4,500
= 3.21 years
In 3.21 yeas, the invested amount is recovered.
