Explanation:
Fixed and variable costs
A fixed cost is expected to be constant for a short term period whilst a variable cost is expected to vary in direct proportion to the number of units produced in this case it is the individual classes.
Depreciation expense on classroom building and on computers is a fixed cost that is expected to remain constant and the instructor wage varies with the number of classes thus a variable cost.
Direct and Indirect costs
A direct cost can be directly traced to the cost object by observation whist the indirect cost can not be directly traced on a cost object.
The instructors wage is a direct cost, his effort is seen with the success of the classes whist the depreciation expenses are indirect costs.
