Due to its poor showing, consideration is being given to closing Store B. Studies show that if Store B is closed, one-fourth of its traceable fixed expenses will continue unchanged. The studies also show that closing Store B would result in a 25 percent increase in sales in Store A. The company allocates common fixed expenses to the stores on the basis of sales dollars.
