Northern is considering closing Store I. If Store I closed, one-half of its traceable fixed expenses would continue to be incurred. Also, the closing of Store I would result in a 10% 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.
