Escher Skateboards has been manufacturing its own wheels for its skateboards. The company is currently operating at 100% capacity, and variable manufacturing overhead is charged to production at the rate of 30% of direct labour cost. The direct materials and direct labour cost per unit to make the wheels are $1.50 and $1.80, respectively. Normal production is 200,000 wheels per year. A supplier offers to make the wheels at a price of $4 each. If the skateboard company accepts this offer, all variable manufacturing costs will be eliminated, but the $42,000 of fixed manufacturing overhead currently being charged to the skateboard wheels will have to be absorbed by other products. Required: a. Prepare the incremental analysis for the decision to make or buy the wheels. (5 marks) b. Should Escher Skateboard buy the wheels from the outside supplier? Justify your answer. (2 marks) c. What 2 (two) qualitative factors should also be considered in making the decision? (3 marks)
