Answer :
Answer:
The tennis department relevant costs (avoidable costs) are variable manufacturing costs ($400,000) and product design ($110,000).
Explanation:
First of all Chris Co. should eliminate its surfing department (since it is not profitable) only if it can use their production facilities to make something else that does generate profit or just sell that facility.
surfing department net profit = $500,000 - $610,000 = -$110,000 or $110,000 net loss
The department's major loss comes from the allocation of $100,000 in facility level costs, but these costs are not relevant or avoidable. Relevant costs are costs that can be avoided by making a business decision like closing a business department.
