A project is one week long $($Mon$-$Fri$)$ and has four tasks, A$,$ B$,$ C and D$.$ The tasks were initially estimated to have daily costs of R $50,$ R$100,$ R$200$ and R$100$ respectively. However, by end of Tuesday, Task A is $100\%$ complete, task B is $90\%$ complete and C is $30\%$ complete. $($See Gantt chart below$).$
