The following information was taken from the annual manufacturing overhead cost budget of Waterway Company Variable manufacturing overhead costs Fixed manufacturing overhead costs $35,200 $18,400 Normal production level in labour hours 16,000 Normal production level in units 4,000 Standard labour hours per unit 4 During the year, 3,800 units were produced, 15,400 hours were worked, and the actual manufacturing overhead was $53,020. Actual fixed manufacturing overhead costs equalled the budgeted foxed manufacturing overhead costs. Overhead is applied based on direct labour hours. Calculate the total, fixed, and variable predetermined manufacturing overhead rates. (Round answers to 2 decimal places, e.g. 15.25.)
