X Company's accountant uses account analysis to estimate costs for each month, with machine hours as the independent variable. In September, she did the following cost behavior analysis for three specific cost items:

Cost Item	Total Cost	Variable
Insurance	310500	0
Utilities	272667	272667
Indirect Labor	322238	231539
