The highest and lowest levels of activity for the Denton Company were 54,000 direct labor hours and 36,000 direct labor hours, respectively. If maintenance costs were $320,000 at the 54,000-hour level and $230,000 at the 36,000-hour level, what cost might we expect at an operating level of 40,000 direct labor hours? During the past year, Cutler, Inc., operated within the relevant range of its fixed costs. Monthly production volume during the year ranged from 40,000 to 60,000 units of product and corresponding total manufacturing costs ranged from $4.00 to $3.80 per unit.
