Using a project start time of 0 (or January 1) and a required project com-pletion time of 180 days (or June 30), calculate the ES, EF, LS, and LF times and TS for each activity. If your calculations result in a project schedule with negative TS, revise the project scope, activity estimated durations, and/or sequence or dependent relationships among activities to arrive at an accept-able baseline schedule for completing the project within 180 days (or by June 30). Describe the revisions you made answers powerpoint

Michigan mattress company is considering the purchase of land and the construction of a new plant. the land, which would be bought immediately (at t = 0), has a cost of $100,000 and the building, which would be erected at the end of the first year (t = 1), would cost $500,000. it is estimated that the firm's afterminustax cash flow will increase by $100,000 starting at the end of the second year, and that this incremental flow would increase at a 10 percent rate annually over the next 10 years. what is the approximate payback period?
