Answer:
3.72 years
Step-by-step explanation:
The cash payback period of this investment is the initial investment of $142,104 divided by net increase in cash in cash flow per period.
Cash Payback Period = Initial Investment /Net increase Cash Flow per Period
Net increase in cash flow per period=$80,000-$41,800=$38,200
Cash payback period=$142,104/$38,200=3.72 years
It would take 3 years 9 months(0.72*12 months) for the project to pay back its initial investment of $142,104
