XYZ Company uses the formula y = a +bX to predict and analyze overhead costs. In the previous year, XYZ used $1,750 per month for the a factor and $0.35 for the bfactor in applying overhead. XYZ has used direct labour hours in the past, but is wondering whether overhead behaviour is more closely associated with machine hours. The following data have been generated for consideration: Month 2 3 4 5 Machine Hours 435 460 400 480 515 422 Overhead Costs $2,560 $2,970 $2.486 $2,570 $2.785 $2,495 6 (a) Determine the freed and variable values, using machine hours. (Round variable cost per machine hour to 2 decimal places 15.25 and fed cost to decimal places, 3.525) Fixed Cost $ Variable Cost S per machine hour
