Due to its poor showing, consideration is being given to closing Store B. Studies show that if Store B is closed, one-third of its traceable fixed expenses will continue unchanged. The studies also show that closing Store B would result in a 50 percent increase in sales in Store A. The company allocates common fixed expenses to the stores on the basis of sales dollars.

Compute the overall increase or decrease in the company's operating income if Store B is closed. Show your work!
