Answer:
The amount of maintenance costs allocated to each operating department is $159,900 to mixing and $86,100 to bottling
Explanation:
In order to determine the amount of maintenance costs allocated to each operating department we would have to calculate first the percentage of area for each deparment as follows:
Particular    Area in square feet     %
mixing          27,235              65
bottling         14,665              35
Total Area      41,900              100
Therefore, if the maintentance cost is $246,000, the amount of maintenance costs allocated to each operating department is as follows:
Particular         %          Allocation of expense
mixing          65              159,900=246,000×65/100
bottling         35              86,100=246,000×35/100
              100              246,000
