The estimated duration of the pouring concrete activities in a commercial building project is $30$ days. After $18$ days, the project manager receives the following information

$\backslash$table$[[$Activity$,$Total quantity $(m3),$Total budget,Actual quantity $(m3),$Actual cost$],[$A$,20,000,800,000,15,000,750,000],[$B$,11,000,550,000,8,000,320,000],[$C$,9,000,180,000,3,000,75,000],[$D$,10,000,700,000,0,0]]$
