Predetermined OH Lansing Mfg. prepared the following annual abbreviated flexible budget for different levels of machine hours: 32.000 35,200 38,400 41,600 Vanable manufacturing overhead $64000 $70,400 $76.800 $200 Fad manufacturing overhead 260.000 260,000 260,000 260,000 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. (1) Units of production L Machine hours Variable OH Rate Fixed Of Rate b. Calculate the combined predetermined OH rate using (1) units of product and machine hours Note: Do not round your answers Units of production Machine hours Combined Rate Assume that all actual overhead costs are equal to expected overhead costs for the year, but that Lanung Mg produced 8,800 units of product, if the separate rates based on units of product calculated in (a) were used to apply overhead whal amounts of underapplied or aver applied variable and fixed overhead exist at year-end Note: Do not use a negative sign with your answer.
