Davis Stores sells clothing in 15 stores located around the southwestern United States. The managers at Davis are considering expanding by opening new stores and are interested in estimating costs in potential new locations. They believe that costs are driven in large part by store volume measured by revenue. During a discussion, one of the managers suggests that number of employees might be better at explaining cost than store revenues. As a result of that suggestion, managers collected the following information from last years operations (revenues and costs in thousands of dollars):

Store	Revenues	Costs	Employees
101	$4,539	$2,388	31
102	6,449	4,781	47
103	5,163	2,719	38
104	4,149	2,602	30
105	4,795	3,440	35
106	3,899	2,474	44
107	6,824	2,802	28
108	3,570	3,951	40
109	2,500	1,955	26
110	6,250	3,917	34
111	6,206	4,181	35
112	2,750	5,939	55
113	4,843	3,257	44
