(Round the variable cost per kilometer to 3 decimal places. Omit the "$" sign in your response.) 2.Express the variable and fixed costs in the form Y = a + bX. (Round the variable cost per kilometer to 3 decimal places. Omit the "$" sign in your response.) 3.If a truck were driven 105,000 kilometers during a year, what total cost would you expect to be incurred?
