We Deliver operates a fleet of delivery trucks in Halifax. Analysis shows that if a truck is driven 114,000 kilometres during a year, the average operating cost is 10.9 cents ($0.109) per kilometre. If a truck is driven only 79,000 kilometres during a year, the average operating cost increases to 12.9 cents ($0.129) per kilometre. Required: 1. Using the high-low method, estimate the variable and fixed cost elements of the annual cost of truck operation. (Do not round your intermediate calculations. Round the "Variable cost per kilometer" to 3 decimal places.) 2. Express the variable and fixed costs in the form Y=a+bX. (Do not round your intermediate calculations. Round the "Variable cost per kilometer" to 3 decimal places.) 3. If a truck were driven 124,400 kilometres during a year, what total cost would you expect to be incurred? (Do not round intermediate calculations. Round the "Variable cost per kilometer" to 3 decimal places.)
