Suppose Department X is 8,000 square feet, Department Y is 5,000 square feet, and Department Z is 6,000 square feet. What's the
den301095 [7]

Answer:

31.6%

Step-by-step explanation:

it is given that

Area of Department X = 8,000  square feet

Area of Department Y = 5,000 square feet

Area of Department Z = 6,000 square feet

now the total area = 8000+5000+6000

                               =19,000 square feet

Percentage of area covered by Department Z = \frac{area of Department Z}{total area }100%

                                               =\frac{6000}{19000} 100 %

                                                 =31.6 %

percentage of overhead expenses applied to Department Z = percentage of area covered by Department Z

hence we have,

percentage of overhead expenses applied to Department Z  = 31.6%
