Please explain how to calculate the payback period for project B

\begin{tabular}{|l|r|r|} \hline Cash Flow & A & B \\ \hline Cost & $12,000 & $100,000 \\ \hline Cash flow year 1 & $4,800 & $40,000 \\ \hline Cash flow year 2 & $4,800 & $30,000 \\ \hline Cash flow year 3 & $4,800 & $20,000 \\ \hline Cash flow year 4 & $4,800 & $10,000 \\ \hline Cash flow year 5 & $4,800 & $0 \\ \hline Cash flow year 6 & $4,800 & $0 \\ \hline \end{tabular} Payback period. Given the cash flow of two projects-A and B-in the following table, , and using the payback period decision model, which project(s) do you accept and which project(s) do you reject if you have a 3-year cutoff period for recapturing the initial cash outflow? For payback period calculations, assume that the cash flow is equally distributed over the year. What is the payback period for project A? years (Round to one decimal place.) With a 3-year cutoff period for recapturing the initial cash outflow, project A would be (Select from the drop-down menu.) What is the payback period for project B? years (Round to one decimal place.)
