Given$$ Bar$-$None's three$-$year payback$$ period, which of the projects will qualify for$$ acceptance?

b$.$Rank the three projects using their payback period. Which project looks the best using this$$ criterion? Do you agree with this$$ ranking? Why or why$$ not?

c$.$If$$ Bar$-$None uses a discount rate of $9\mathrm{.}9$ percent to analyze$$ projects, what is the discounted payback period for each of the three$$ projects? If the firm still maintains its$$ three$-$year payback policy for the discounted$$ payback, which projects should the firm$$ undertake?
