2. Develop a formula to express the cost behavior exhibited by the company’s maintenance cost.
3. Predict the level of maintenance cost that would be incurred during a month when 34,000 tour miles are driven. (Remember to express your answer in terms of the real.)
4. Build a spreadsheet: Construct an Excel spreadsheet to solve all of the preceding requirements. Show how the solution will change if the following information changes: in March there were 32,000 miles traveled and the cost was 20,000real.
