The CHEG Manufacturing Company wants to develop a cost estimating equation for its monthly cost of electricity. It has the following data: Month Cost of Electricity Direct Labor Hours January $6,750 1,500 April 7,500 1,700 July 8,500 2,000 October 7,250 1,600 Using the high-low method, what is the best equation? O Y = $750 + $5.00x O Y = $750 + $3.50X O Y = $1,500 + $3.50X O Y = $2,000 + $3.50X O Y = $1,500 + $5.00X
