If a truck is driven only 80,000 kilometres during a year, the average operating cost increases to 13.6 cents ($0.136) per kilometre. Required: 1. Using the high-low method, estimate the variable and fixed cost elements of the annual cost of truck operation. 2. Express the variable and fixed costs in the form Y a + bx. 3.
