Brindis Babysitting Center currently rents a 1200 sq foot facility for her 20-child facility. Her business has gotten five stars on Yelp, which has prompted more applications. She has to make a decision between expanding her operations to an 1,800 sq foot facility or staying in the current facility. Shown is the cost data of the options:

	Expand	Stay
Children served	30	20
Annual rent	1500	1000
Utilities	500	300
Food and materials	2100	1400
Direct labor	6000	4000
Moving cost	5000

What is the differential cost of the two alternatives: A) move to a larger facility or B) stay in current facility?
