This is real world data, so it is not as "pretty" as data that might be made up for an accounting class. The traditional format is used financial reporting It is the format you learned in ACCOUNT 244. In this chapter, and this course, we work primarily with the contribution format income statement. This is the in-class portion of the assignment. Requirement 1: To convert the traditional format into contribution format, we must categorize each expense as variable, or fixed. Revenue is variable per unit sold. Some of the expenses are already marked as Variable or Fixed. Conveyor Services is a mixed cost; we will deal with that shortly. For now, complete the table beside the income statement by Indicating whether each expense is Variable or Fixed. You must do this based on your understanding of how the cost will react to changes in the satt of concrete poured. If you have questions about pouring concrete and you can't find the answers, I can help point you in the right direction. Requirement 2: Conveyor Services is a mixed cost. The company has determined that when 100,000 saft of concrete are poured, conveyer services costs $107,379 and when 200,000 satt of concrete are poured, conveyor services cost $204,379. Write the cost function for Conveyor Services in the form Y=a + bx.
