Fixed expenses consist of $$300,000$ of common costs allocated to the three products based on relative sales, as well as direct fixed expenses unique to each model of $$30,000($Tingler$),$ $$80,000($Shocker$),$ and $$35,000($Stunner$).$ The common costs will be incurred regardless of how many models are produced. The direct fixed expenses would be eliminated if that model is phased out.

James Watt, an executive with the company, feels the Stunner line should be discontinued to increase the company's net income.
