Answer:
variable cost = 0.074; fixed cost = 4,200
Explanation:
We will formulate (2) total cost equations in the form (TC = FC + VC * number of kilometres).
TC = Total cost for 105,000km at 11.4 cent average operating cost = 105,000 * 0.114 = $11,970.
TC for 70,000km at 13.4 cent = 70,000 * 0.134 = $9,380.
Therefore
(Equation 1): $11,970 = F + 105,000V
Equation 2): $9.380 = F + 70,000V
Using the high-low method, we will estimate "V" as follows.
($11,970 - $9,380) = (105,000 - 70,000)V
= $2,590 = 35,000V
= V = Variable Cost = $2,590/35,000 = 0.074.
From equation (1), we can deduce that F = 11,970 - 105,000V
= F = 11,970 - (105,000*0.074)
= F - Fixed Cost = $4,200.
