Chapter 19 CUT definitions of those ter of the cost best range of volume, when wes by a lump sum The left column lists several cost classifications. The right column presents short definition costs. In the blank space beside each of the numbers in the right column, write the letter of the described by the definition. A. Total cost - 1. This cost is the combined amount of all the other costs. B. Mixed cost 2. This cost remains constant over a limited range of volume c. Variable cost it reaches the end of its limited range, it changes by a lun D. Curvilinear cost and remains at that level until it exceeds another limited rar E. Step-wise cost 3. This cost has a component that remains the same over all yolu levels and another component that increases in direct proportio F. Fixed cost to increases in volume. 4. This cost increases when volume increases, but the increase is not constant for each unit produced. _5. This cost remains constant over all volume levels within the pro- ductive capacity for the planning period. 6. This cost increases in direct proportion to increases in volume; its amount is constant for each unit produced
