Answer:
Payback period = 3 years 6 months
Plant shall be accepted.
Step-by-step explanation:
Payback period refers to the term of period in which the cost of the asset will be recovered through the revenues generated via that asset.
If payback period is less than the expected life of asset the project or asset shall be accepted and invested in.
In the given case,
Purchase price of asset = $1,100,000
Cash generated each year = $314,000
Thus, payback period =

that means 3 years and 12
0.503 = 6.036 months
This is not the discounted payback period.
Here discount rate is not provided, also the life of plant is expected to be 6 years since payback is less that is 3 years and 6 months the purchase of plant offer shall be taken.
Correct answer
Payback period = 3 years 6 months
Plant shall be accepted.
