CVP analysis, shoe stores.

The HighStep Shoe Company operates a chain of shoe stores that sell 10 different styles of inexpensive mens shoes with identical unit costs and selling prices. A unit is defined as a pair of shoes. Each store has a store manager who is paid a fixed salary. Individual salespeople receive a fixed salary and a sales commission.
