Fuel expense | = | $ | 5.71 | * | passenger | + | $ | 10,043 |
Passenger miles: | ||||||||
Fuel expense | = | $ | 0.01 | * | passenger mile | + | $ | 17,867 |
Train miles: | ||||||||
Fuel expense | = | $ | 3.80 | * | train mile | + | $ | 12,512 |
Calculations:
(1): Passengers – Here the function is: y = a+bx where y = fuel expense, a = fixed costs and b = variable costs.
Variable cost = (y2-y1)/(x2-x1)
X2 = 2698 (highest no. of passengers) and y2 at this level (fuel expense) = 25459. X1 = 2132 (lowest no. of passengers) and y1 at this level = 22225
Thus variable cost = (25459-22225)/(2698-2132) = 5.71 per passenger.
Fixed cost (or a) = y2-bx2 = 25459 – (5.71*2698) = 10043.22
(2): Passenger miles – Here x2 = 579939 and y2 = 23666. X1 = 375339 and y1 = 21620
Thus variable cost = (23666-21620)/(579939-375339) = 0.01
Fixed cost = y2-bx2 = 23666-(0.01*579939) = 17866.61
(3): Train mile – x2 = 3407 and y2 = 25459. X1 = 2556 and y1 = 22225
Thus variable cost = (25459-22225)/(3407-2556) = 3.80
Fixed costs = y2-bx2 = 25459-(3.80*3407) = 12511.60
