Answer:
The formula for cash payback period is
Initial Investment/Net cash inflow from the investment
So in this case the initial investment is $40,000 and the cash flow increased by the computer is $5,000 so in order to find the cash payback period we will divide 40,000 by 5,000
40,000/5,000=8
The cash payback period is 8 years for the investment in the computer
In this case we ignored the depreciation expense as it is a non cash expense.
