Please help. It is my final. I need to know how to do it with the answers.

Assume you are the project manager and based on your customer's requirements you have determined there are four main tasks in a Dream Backyard project and have assigned each a TBC. Specifically, the customer wants the backyard leveled (Task 1 - $10,000); wants a covered outdoor kitchen with a hot tub and firepit (Task 2 - $30,000), a retaining wall with fencing built- in (Task 3 - $20,000), and a pool (Task 4 - $40,000). You estimate this will take 5 weeks to complete. The costs are budgeted as follows: 1 Task 1 Task 2 Task 3 Task 4 TBC 10 30 20 40 Budgeted Per Week (in 000's) 2 3 4 5 6 1 5 10 15 8 6 6 15 20 5 What is the total cumulative TBC? What is TBC at the end of week 4? . Assume 4 weeks have passed and these are the actual costs per week. Task 1 Task 2 Task 3 Task 4 Actual Costs Per Week (in 000's) 1 2 3 4 5 4 2 7 5 4 5 6 1 3 4 10 What is the CAC at the end of week 4? Below is the cumulative percentage of work complete per task per week Task 1 Task 2 Task 3 Task 4 Cumulative Percentage Complete 1 2 3 4 40% 80% 100% 5% 30% 45% 50% 50% 70% 5% 15% 30% 60% What are the CEV, CPI, and CV at the end or week 4
