Required Answer the following using trainees as the measure of activity: (a) Classify cach cost line as variable, fixed, or mixed. (b) Separate each mixed cost into its variable and fixed compo- nents. (c) Calculate the total variable cost per trainee. (d) Calculate the total fixed cost per course. (e) Calculate the contribution margin per trainee. (f) Calculate the number of trainees at which the course will break even. (g) Calculate the profit for a course with 10 trainees. (h) Calculate the profit for a course with 25 trainees. (i) Course 2015.X3 is full. It has 25 trainees registered. One of Arnprior Academic's own employees is to go on the course in addition to the existing 25 trainees. By agreement, the Arnprior HR department is going to be charged "cost", instead of the $500 normally charged to outside customers. How much will that be? 6) is the break-even model a good description of Arnprior Aca- demic's course activities
