Answer:
6 years
Step-by-step explanation:
Payback period is the length of time required for the total cashflows to equal the initial capital investment.
Note : Payback method uses cashflows not profits
Determination of Annual Cash flow :
After-tax net income $2,000
Add depreciation $1,500
Annual cash flow $3,500
Therefore,
Payback period = $3,500 + $3,500 + $3,500 + $3,500 + $3,500 + $3,500+ $3,500
= $21,000
Therefore, the payback period is 6 years
