You are in charge of a project at the local community center. The center needs to remodel one of the rooms in time for the start of a new program. Delays in the project mean that the center must rent other space at a nearby church at additional cost. Time and cost data for your project are contained in 7.10. Your interest is in minimizing the cost of theproject to the community center.a. Using the normal times for each activity, what is the earliest date you can complete the project?b. Suppose the variable overhead costs are $50 per day for your project. Also, suppose that the center must pay $40 per day for a temporary room on day 15 or beyond. Find the minimum-cost project schedule.
d. How long the program is expected to finish? e. Determine the slack time for each activity using either LS & ES or LF and EF. f. What is the probability of finishing in 75 days?
