Need help

You have a project to build a new fence. The fence is four sided. Each side is to take one day to build and is budgeted for $1,000 per side. The sides are planned to be completed one after the other. Today is the end of day three. The third side is 50% complete. The costs per side are below. Side 1 = $1000 Side 2 = $1300 Side 3 = $800 Assume any future spending will be at the current spending rate.

What is the ETC?

Which of the following projects would you LEAST want to have as your first project in a company - based only on the charts below? (Assumption is that you want to be on the most likely to succeed project to look good for your new boss.)

NOTE: Projects are indicted with a small letter in parenthesis below the chart. Top left is (a), Top right is (b), Bottom left is (c), Bottom right is (d).

Any, they all look likely to succeed
		None, they are all over determined
		(d)
		(a)
		(b)
		(c)

why is the answer a and not c or d

(a)+SV1+CCV (b)+SV,+CV (c) SV1CV (d) SV,CV
