Please help answer. How do I give an accurate expenditure plan with such generic information PPA602?

You are in the role of a chief operating officer. A board of directors has requested that you prepare a summary of the issues involved in a $50 million expansion. Because of local political and uncertain national financial policy of the to-be-elected national officials they may have to scale the expansion back to $25 million. Prepare a report for the mayor and city council on your proposed expenditure plan
