The Gourmand Cooking School runs short cooking courses at its small campus. Management has identified two cost drivers it uses in its budgeting and performance reports$$the number of courses and the total number of students. For example, the school might run two courses in a month and have a total of $65$ students enrolled in those two courses. Data concerning the company$$s cost formulas appear below:

Fixed Cost per Month Cost per Course Cost per

Student

Instructor wages $ $2,970$

Utilities $ $1,200$ $ $80$

Campus rent $ $4,700$

Insurance $ $2,000$

Administrative expenses $ $3,800$ $ $45$ $ $4$

For example, administrative expenses should be $$3,800$ per month plus $$45$ per course plus $$4$ per student. The company$$s sales should average $$850$ per student.
