Can someone help with this? A step by step solution would be nice.

The most recent monthly income statement for Benner Stores is given below:

	Total	Store A	Store B
Sales	$1,000,000	$400,000	$600,000
Variable expense	440,000	160,000	280,000
Contribution margin	560,000	240,000	320,000
Traceable fixed expense	380,000	100,000	280,000
Store segment margin	180,000	140,000	40,000
Common fixed expenses	220,000	90,000	130,000
Net operating income	($40,000)	$50,000	($90,000)

Due to its poor showing, consideration is being given to closing store B. Studies show that is 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 10 percent increase in sales in Store A. The company allocates common fixed expenses to the stores on the basis of sales dollars. However, 30% of the common fixed costs can be eliminated if store B closes.

1. Determine the monthly financial advantage (disadvantage) of closing Store B.

2. What would be your recommendation for Benners management?

3. If the one-fourth of Store Bs traceable fixed expenses that remain unchanged are its lease payments, when would you want to reconsider your recommendation from question 2? Why? Show numbers.
