TO SOLVE THIS PROBLEM WE NEED TO KNOW HOW MANY HOURS ARE REQUIRED FOR THE REPAIR WORK FROM EACH ESTIMATOR.
162+32X=? WHERE X IS THE NUMBER OF HOURS FOR THE REPAIRS.
144+35X=?
----------------------------------------------
IF X=1 THEN 162+32=194 & 144+35=179 ITZA BEST.
IF X=5 THEN 162+32*5=162+160=322 & 144+35*5=144+175=319 ITZA BEST.
IF X=8 THEN 162+32*8=162+256=418 & 144+35*8=144+280=424 CARS BEST.
