Angie Silva has recently opened The Sandal Shop in Brisbane, Australia, a store that specializes in fashionable sandals. In time, she hopes to open a chain of sandal shops. As a first step, she has gathered the following data for her new store:

Sales price per pair of sandals	$	34
Variable expenses per pair of sandals		17
Contribution margin per pair of sandals	$	17
Fixed expenses per year:
Building rental	$	12,800
Equipment depreciation		12,800
Selling		10,200
Administrative		15,200
Total fixed expenses	$	51,000

4. Angie now has two salespersons working in the storeone full time and one part time. It will cost her an additional $8,000 per year to convert the part-time position to a full-time position. Angie believes that the change would increase annual sales by $40,800. Should she convert the position? Use the incremental approach.
