Isaacson's Fine Furnishings manufactures upscale custom furniture. Isaacson's currently uses a plantwide overhead rate based on direct labor hours to allocate its $1,100,000 of manufacturing overhead to individual jobs. However, Delores Cermak,owner and CEO, is considering refining the company's costing system by using departmental overhead rates. Currently, the Machining Department incurs $740,000 of manufacturing overhead while the Finishing Department incurs $360,000 of manufacturing overhead. Cermak has identified machine hours (MH) as the primary manufacturing overhead cost driver in the Machining Department and direct labor (DL) hours as the primary cost driver in the Finishing Department.

The Isaacson's plant completed Jobs 450 and 455 on May 15. Both jobs incurred a total of 6 DL hours throughout the entire production process. Job 450 incurred 1 MH in the Machining Department and 5 DL hours in the Finishing Department (the other DL hour occurred in the Machining Department). Job 455 incurred 5 MH in the Machining Department and 4 DL hours in the Finishing Department (the other two DL hours occurred in the Machining Department

1.Compute the plantwide overhead rate assuming that Isaacson's expects to incur 27,500total DL hours during the year.

2. Compute departmental overhead rates assuming that Isaacson's expects to incur 14,800 MH in the Machining Department and 18,000 DL hours in the Finishing Department during the year.

3.If Isaacson's continues to use the plantwide overhead rate, how much manufacturing overhead would be allocated to Job 450 and Job 455? First identify the formula, then calculate the amount of manufacturing overhead that would be allocated to the jobs if the plantwide overhead rate is used. (Round your answers to the nearest whole dollar.)

4.If Isaacson'suses departmental overhead rates, how much manufacturing overhead would be allocated to Job 450 and Job 455? Use the following table to calculate the amount of manufacturing overhead that would be allocated to the jobs if the departmental overhead rates are used. (Round your answers to the nearest whole dollar.)
