Predetermined OH Lansing Mfg. prepared the following annual abbreviated flexible budget for different levels of machine hours: 32,000 35,200 38,400 41,000 Variable manufacturing overhead $14,000 $70,000 $76.800 $83,200 Fixed manufacturing overhead 260.000 260,000 250,000 200,000 Each product requires four hours of machine time, and the company expects to produce 8,000units for the year. Production is expected to be evenly distributed throughout the year. a. Calculate separate predetermined variable and fixed OH rates using as the basis of application (1) units of production and (2) machine hours. Note: Do not round your answers. Variable OH Rate Fixed OH Rate (1) Units of production (2) Machine hours b. Calculate the combined predetermined OH rate using (1) units of product and (2) machine hours. Note: Do not round your answers. Combined Rate (1) Units of production (2) Machine hours c. Assume that all actual overhead costs are equal to expected overhead costs for the year, but that Lansing Mfg. produced 2,800 units of product. If the separate rates based on units of product calculated in (a) were used to apply overhead, what amounts of underapplied or overapplied variable and fixed overhead exist at year-end? Note: Do not use a negative sign with your answer. Variable O 0 Fixed OH $ 0 Check
