Answer:
Cash payback period= 3.2 years.
Explanation:
Lets first understand what a cash payback period is. As the name suggest, payback period is the time duration within which a business recovers it's investment and/or capital investment and the payback period is expressed in number of years. The formula for payback period is as follows:
Payback period= initial investment ÷ annual cash-flows
In the question annual operating income is given just for distraction.
payback period = $324000 ÷ 100000
payback period= 3.2 years.
This means if Hayden company decides to invest in the machine, it would recover the cost of machine (i.e it's investment) in approximately three and half years.
