The following problem is an example of MIXED COSTS : This costs contains both variable and fixed components. Also known semi-variables. The linear equation Y = A + BX (page 38 in the book) show the exhibit 2-5 help the manager to separate each cost in fixed and variable.
1. The WESTERN HOTEL has accumulated records of the total electrical costs of the hotel and number of occupancy – days over the last year. An occupancy-day represents a room rented out for one day. The hotel’s business is highly seasonal, with peaks occurring during the ski season and in the summer.

HINT: The cost driver is Occupancy days (which causes the cost to occur) Determine the regression formula to be able to project costs from September to December and then the first 4 months of next year.

A: Variable Cost Element = Change in Cost $ = 5,822 / 3,068 = 1.90 per day op
change of activity
B Fixed Cost Element = Total cost – Variable cost element
$ 8,111 – ( 1.90 x 3,608 Occup days)
8.111 – 6,855 = 1,256 , fixed cost
Then the equation is : Y = A + BX
Y = 1,256 + 1.90(X)
Note: To complete the projections from September to December, all you have to do is replace the X with the COST DRIVER OF EACH MONTH and you get the cost for each month of electricity and you can project the months of next year.

Cost Formula : Y = 1,256 + 1.90(X) :
For Jan - 2017 :
Number of Occupancy Days = 3,500
Therefore, Electrical Cost (Y) = 1,256 + 1.90 x (3,500) = 1,256 + 6,650 = $7,906
For Feb - 2017 :
Number of Occupancy Days : 4,050
Therefore, Electrical Cost (Y) = 1,256 + 1.90 x (4,050) = 1,256 + 7,695 = $8,951
For Mar - 2017 :
Number of Occupancy Days : 4,800
Therefore, Electrical Cost (Y) = 1,256 + 1.90 x (4,800) = 1,256 + 9,120 = $10,376
For Apr - 2017 :
Number of Occupancy Days : 2,500
Therefore, Electrical Cost (Y) = 1,256 + 1.90 x (2,500) = 1,256 + 4,750 = $6,006
