Task time estimates for the modification of an assembly line at Jim Goodale's Carbondale, Illinois, factory are as follows:

$\backslash$table$[[$Actlvity$,\backslash$table$[[$Time$],[($in hours$)]],$Immediate Predecessor$($s$)],[$A$,7\mathrm{.}0,-],[$B$,6\mathrm{.}7,-],[$C$,5\mathrm{.}0,$A$],[$D$,8\mathrm{.}0,$B$,$ C$],[$E$,4\mathrm{.}8,$B$,$ C$],[$F$,7\mathrm{.}7,$D$],[$G$,6\mathrm{.}0,$E$,$ F$]]$

This exercise contains only part a$.$
