The Hard Rock Mining Company is developing cost formulas for management planning and decision-making purposes. The company's cost analyst has concluded that utilities cost is a mixed cost, and he is attempting to find a base that correlates with the cost. The controller has suggested that tons mined might be a good base to use in developing a cost formula. The production superintendent disagrees; she thinks that direct labor-hours would be a better base. The cost analyst has decided to try both bases and has assembled the following information: Direct Labor 4.20 Quarter Year 11 Tons Hined Hours Utilities Cost First 31,000 6,600 $66,000 Second 20,000 4,600 $ 61,000 Third 36,000 5,500 $76,000 Fourth 28,000 7,600 $91,000 Year 21 First 34,000 13,200 $116,000 Second 41,000 13,000 $121,000 Third 46,000 Fourth 44,000 11,200 14,200 $101,000 $136,000 2. Using the least-squares regression method, estimate the variable utilities cost per direct labor-hour and the total fixed utilities cost per quarter. Express these estimates in the form Y a bX (Round the Variable cost to 2 decimal places and Fixed Cost to the nearest whole dollar amount.) Y
