Hoi Chong Transport, Limited, operates a fleet of delivery trucks in Singapore. The company has determined that if a truck is driven 90,000 kllometers during a year, the average operating cost is 9.1 cents per kllometer. If a truck is driven only 60,000 killometers during a year, the average operating cost increases to 9.8 cents per kilometer. Required: 1. Using the high-low method, estimate the variable operating cost per kilometer and the annual fixed operating cost associated with the fleet of trucks. 2. Express the variable and fixed costs in the form Y=a+bX . 3. If a truck were driven 75,000 kilometers during a year, what total operating cost would you expect to be incurred? Complete this question by entering your answers in the tabs below. Using the high-low method, estimate the variable operating cost per kllometer and the annual fixed operating cost associated with the fleet of trucks. (Do not round your intermediate calculations. Round the Variable cost per kilometer to 3 decimal places.)
