Andretti Company has a single product called a Dak. The company normally produces and sells $81,000$ Daks each year at a selling price of $$60$ per unit. The company$$s unit costs at this level of activity are given below:

Direct materials $ $9\mathrm{.}50$

Direct labor $10\mathrm{.}00$

Variable manufacturing overhead $3\mathrm{.}80$

Fixed manufacturing overhead $5\mathrm{.}00($$$405,000$ total$)$

Variable selling expenses $3\mathrm{.}70$

Fixed selling expenses $4\mathrm{.}00($$$324,000$ total$)$

Total cost per unit $ $36\mathrm{.}00$

A number of questions relating to the production and sale of Daks follow. Each question is independent.

Required:

$1-$a$.$ Assume Andretti Company has sufficient capacity to produce $109,350$ Daks each year without any increase in fixed manufacturing overhead costs. The company could increase its unit sales by $35\%$ above the present $81,000$ units each year if it increased fixed selling expenses by $$110,000.$ What is the financial advantage $($disadvantage$)$ of investing an additional $$110,000$ in fixed selling expenses?

$1-$b$.$ Would the additional investment be justified?

$2.$ Assume Andretti Company has sufficient capacity to produce $109,350$ Daks each year. A customer in a foreign market wants to purchase $28,350$ Daks. If Andretti accepts this order, it would pay import duties on the Daks of $$1\mathrm{.}70$ per unit and an additional $$25,515$ for permits and licenses. The only selling costs associated with the order would be $$1\mathrm{.}90$ per unit shipping cost. What is the break$-$even price per unit on this order?

$3.$ The company has $500$ Daks on hand with some irregularities that make it impossible to sell them at the normal price through regular distribution channels. What unit cost figure is relevant for setting a minimum selling price to liquidate these units?

$4.$ Due to a strike in its supplier$$s plant, Andretti Company is unable to purchase more material for the production of Daks. The strike is expected to last for two months. Andretti Company has enough material on hand to operate at $25\%$ of normal levels for the two$-$month period. As an alternative, Andretti could close its plant down entirely for the two months. If the plant were closed, fixed manufacturing overhead costs would continue at $40\%$ of their normal level during the two$-$month period and the fixed selling expenses would be reduced by $20\%$ during the two$-$month period.

How much total contribution margin will Andretti forgo if it closes the plant for two months?

How much total fixed cost will the company avoid if it closes the plant for two months?

What is the financial advantage $($disadvantage$)$ of closing the plant for the two$-$month period?

Should Andretti close the plant for two months?

$5.$ An outside manufacturer offered to produce $81,000$ Daks and ship them directly to Andretti$$s customers. If Andretti Company accepts this offer, the facilities that it uses to produce Daks would be idle; however, fixed manufacturing overhead costs would be reduced by $75\%.$ Because the outside manufacturer would pay for all shipping costs, the variable selling expenses would be only two$-$thirds of their present amount. What is Andretti$$s avoidable cost per unit it should compare to the price quoted by the outside manufacturer?
