A contractor agreed to build 30 model houses in 90 days at a price of RM 800 per unit. 20 days later, the contractor has finished 8 model houses with an actual total cost (that includes his overhead and profit) of RM 6800. What is the status of the projects?

Calculate: i) BCWS ii) BCWP iii) ACWP iv) CV v) SV

Assume that the work is sequential and not parallel (i.e., the contractor works on one unit till it is finished then starts the next unit and so on)
