both are the same question

A construction company is building an apartment with 36 flats. All the flats are already sold and the relevant amounts were paid by the buyers. Although the flats are completed some general works in the apartment (electricity and water connections, installation of central generator and painting of stairs etc.) are still remaining. The flat owners are complaining because despite they have paid their houses, they can't move in on the date promised by the company. The company decided to complete the remaining works as soon as possible. They allocated a budget of $450,000 for the Direct Costs and promised the flat owners that the apartment will be ready in 20 weeks. The remaining work has been analyzed by the company and broken down into eight activities. The results of this analysis are as follows: Activity A B Pre- Durations, weeks requisite Normal Crash 5 4. 6 4. A 4 3 A 3 3 A 1 1 E 4. 4.

Show all (b) Can the 20 week promise to flat owners be met within the budget available? Show all your work (c) Determine a 19 week schedule for the venture. Is this schedule feasible to the company? Why? (d) The flat owners offered the company to accept a delay in moving into their flats, provided they are compensated by $1,000 each for every week's delay over 20 weeks. Tabulate all feasible options for the company. What is now the cheapest option for the company? Note. Indirect Costs = 80,000 + 1,000
