Adriana Corporation manufactures football equipment. In planning for next year, the managers want to understand the relation between activity and overhead costs. Discussions with the plant supervisor suggest that overhead seems to vary with labor-hours, machine-hours, or both. The following data were collected from last year's operations. Month Labor-Hours Machine-Hours Overhead Costs 1 730 1,348 $ 102,687 2 715 1,413 103,704 10 11 12 3456789012 690 1,527 109,971 750 1,446 108,354 775 1,584 116,142 755 1,570 114,409 735 1,381 107,067 715 1,317 102,014 705 1,447 106,334 790 1,535 113,180 675 1,286 715 1,608 97,966 110,363 Required: a. Use the high-low method to estimate the fixed and variable portions of overhead costs based on machine-hours. b. Managers expect the plant to operate at a monthly average of 1,500 machine-hours next year. What are the estimated monthly overhead costs, assuming no inflation? Complete this question by entering your answers in the tabs below. Required A Required B Use the high-low method to estimate the fixed and variable portions of overhead costs based on machine-hours. (Round "Variable cost" answer to 2 decimal places.)
