Assume that a company has two cost drivers number of courses and number of students. The planned number of courses and students were 5 and 100, respectively. The actual number of courses and students were 6 and 110, respectively. One of the company's expenses is influenced by both cost drivers and it has a fixed element as well. Its cost formulas are $50 per course, $5 per student, and $1,000 per period. The activity variance for this expense would be: Multiple Choice $100 F $100 U $200 F $200 U
