Both Proposal M, and N Cost $800,000, Have a 6-Year

Both proposal M, and N cost $800,000, have a 6-year life, and have expected total cash flows of $1,200,000. Proposal M is expected to provide equal annual net cash flows of $200,000, while the net cash flows for Proposal N are as follows:
$\begin{array}{ll}\$ 250,000 & \text { Year 1 } \\\$ 225,000 & \text { Year 2 } \\\$ 200,000 & \text { Year 3 } \\\$ 200,000 & \text { Year 4 } \\\$ 175,000 & \text { Year 5 } \\\$ 150,000 & \text { Year 6 }\end{array}$ Determine the cash payback period for each proposal.
