Your answer is partially correct. Waterway Company's manufacturing overhead budget shows total variable costs of $257,400 and total fixed costs of $210,600. Total production in units is expected to be 195,000. It takes 20 minutes to make one unit, and the direct labor rate is $15 per hour. Express the manufacturing overhead rate as (a) a percentage of direct labor cost, and (b) an amount per direct labor hour. (Round manufacturing overhead rate as a percentage of direct labor cost to O decimal places and as an amount per direct labor hour to 2 decimal places, e.g. 125.47.) (a) 4.6 (b) $ 7.2 %
