Hoi Chong Transport, Ltd., operates a fleet of delivery trucks in Singapore. The company has determined that if a truck is driven 147,000 kilometers during a year, the average operating cost is 8.7 cents per kilometer. If a truck is driven only 98,000 kilometers during a year, the average operating cost increases to 9.6 cents per kilometer.

1. Using the high-low method, estimate the variable and fixed cost elements of the annual cost of the truck operation. 2. Express the variable and fixed costs in the form Y = a + bX. 3. If a truck were driven 122,000 kilometers during a year, what total cost would you expect to be incurred?
