I am having a hard time understanding how to allocate overhead costs when there are three support departments. Please show all work. Thanks in advance.

Jasmine Company manufactures both pesticide and liquid fertilizer, with each product manufac- tured in separate departments. Three support departments support the production departments: Power, General Factory, and Purchasing, Budgeted data on the five departments are as follows: Support Departments Producing Departments Power General Factory Purchasing Pesticide Liquid Fertilizer Overhead $90,000 $314,000 $167,000 $78,900 $107,800 Square feet 1,500 1,500 4,200 4,800 Machine hours 1,403 1,345 24,000 8,000 Purchase orders 20 7 120 60 The company does not break overhead into fixed and variable components. The bases for alloca- tion are power-machine hours, general factory-square feet; and purchasing purchase orders. 40 Exercise 7.21 Sequential Method Refer to the data in Exercise 7.20. The company has decided to use the sequential method of allocation instead of the direct method. The support departments are ranked in order of highest cost to lowest cost. Required: 1. Allocate the overhead costs to the producing departments using the sequential method. (Take allocation ratios out to four significant digits. Round allocated costs to the nearest dollar.) 2. Using machine hours, compute departmental overhead rates. (Round the overhead rates to the nearest cent.)
