Answer:
1) a. $15
2) a. $50,000
Explanation:
July: n1 = 4,000; c1 =$110,000
January: n2 = 2,500; c1 =$87,500
1) Using the high/low method, the average variable cost is determine as the difference between the highest and lowest activity costs, divided by the difference between the highest and lowest output:
[tex]VC = \frac{c_1-c_2}{n_1-n_2}=\frac{110,000-87,500}{4,000-2,500}\\ VC=\$15[/tex]
The average variable cost is $15.
2) The total fixed cost is determined by the highest activity cost (c1), subtracted by the product of the highest output and the variable cost (n1 x VC):
[tex]FC = c_1 -(n_1*VC)\\FC = 110,000 - (4,000*15)\\FC=\$50,000[/tex]
Total fixed cost is $50,000.
