Andretti Company has a single product called a Dak. The company normally produces and sells 78,000 Daks each year at a selling price of $49 per unit. The company's unit costs at this level of activity follow: A number of questions relating to the production and sale of Daks follow. Consider each question separately. Required: 1. Assume that Andretti Company has sufficient capacity to produce 150,000 Daks every year without any increase in fixed manutacturing overhead costs. The company currently produces and sells 78,000 units each year. However, it plans to increase the fixed selling expenses by $28,750 in order to increase sales. By how much should sales increase in order to justify the additional $28,750 ? Please compute the percentage increase in sales. (Do not round intermediate calculations. Round up your "units" answers to the nearest whole number and percentage answer to 2 decimal places.) 4. Due to a strike in its supplier's plant, Andretti Company is unable to purchase more materials for the production of Daks. The strike is expected to last for two months. Andretti Company has enough materials on hand to continue to operate at 30% of normal hevels for the two-month period. As an alternative. Andretti could close its plant down entirely for the two months. If the plant were closed, all fixed costs would continue at 50% of their normal level during the two-month period. What would be the dollar advantage or disadvantage of closing the plant for the two month period? (Do not round intermediate calculations.) 5. An outside manufacturer has offered to produce Daks for Andretti Company and to ship them directly to Andretti's customers. If Andretti Company accepts this offer, the facilities that it uses to produce Daks would be idle; however, fixed overhead costs would be reduced by 75% of their present level. Since the outside manufacturer would pay all the costs of shipping, the variable selling costs would be only two thirds of their present amount. Compute the unit cost figure relevant for comparison to whatever quoted price is received from the outside manufacturer. (Do not round intermediote calculations. Round your answer to 2 decimal places.)
