Budgeted cost is $150000. PV = 110, EV = 90, and AC = 80 at week 30. Calculate schedule, cost and time variances, as well as schedule and cost performance indices for Week 30. Then use this information to comment on the project progress at Week 30 (status date). Based on the performance at Week 30, estimate the final project cost (EAC). Will the final project cost be higher or lower than the budgeted cost, and by how much? Also estimate the revised project completion date. Will the project complete sooner or later than the planned completion date, and by how many weeks
