the question is same but a little bit difference in the question is Northern is considering closing Store I. If Store I closed, $25\%$ of its traceable fixed expenses would continue to be incurred. Also, the closing of Store I would result in a $20\%$ decrease in contribution margin in Store II$.$ Northern allocates common fixed expenses based on sales dollars and none of these costs would be saved if a store were shut down.
