The Required Return for this project is 12% and the Critical Acceptance Level is 2.75 years.
1 Using excel to calculate each of the following; show the steps:
(a) Payback Period for Option A & Option B
(b) Internal Rate of Return for Option A & Option B
(c) Net Present Value for Option A & Option B

2 Using the calculations above, clearly present the results for Option A and Option B as though for an audience of city council members.
3 The city council says they can adopt only one of the projects this year. Pick one and justify the choice to the city council.
4 You are getting pushback from the city engineer that both projects are vital and should be done this year. You really want to find a way to make both projects happen. Provide a solution that will allow both projects to be implemented.

Please see the attached excel file
