Answer:
Fixed component 5,237
Variablwe 7.4 per hour
cost formula
[tex]C_{dl} = 7.4DL_h+5,237[/tex]
Explanation:
We list and highlight
January $7,000 360
February 8,140 550
March 9,899 630
April 9,787 610
May 8,490 480
June 7,450 350
July 9,490 570
August 7,531 310
We subtract low from high:
[tex]\left[\begin{array}{ccc}High&630&9899\\Low&310&7531\\Diference&320&2368\\\end{array}\right][/tex]
Then we solve for the variable as we are given the fact that 320 hours generate 2,368 labor cost
2,368 / 320 = 7.4 variable labor
then we solve for fixed cost:
Total Cost 9899
Variable 630 x 7.4 = (4662)
Fixed Cost 5237
