We Deliver operates a fleet of delivery trucks in Halifax. Analysis shows that if a truck is driven 121.000 kilometres during a year, the average operating cost is 11.2 cents ($0.112) per kilometre. If a truck is driven only 88,000 kilometres during a year, the average operating cost increases to 13.2 cents ($0.132) 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.)

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 107.800 kilometres during a year. What total cost would you expect to be incurred? (Do not round intermediate calculations.
