Additional information for the problem:
Total selling and customer service costs depend on the number of customers that the company has created capacity to support, not the actual number of customers. Total purchasing and administrative costs depend on purchasing and admin capacity that the company has created (in terms of the number of distinct designs that can be purchased and adminstered.) Purchasing and administrative costs do not depend on the actual number of distinct clothing designs purchased. The company purchased 930 designs in 2004 and 820 designs in 2005.
