please solve with explanation

Polaski Company manufactures and sells a single product called a Ret. Operating at capacity, the company can produce and sell 38,000 Rets per year. Costs associated with this level of production and sales are as follows: Direct materials Direct labour Variable manufacturing overhead Fixed manufacturing overhead Variable selling expense Fixed selling expense Unit $20.00 13.00 8.00 14.00 4.00 6.00 Total $760,000 494,000 304,000 532,000 152.000 228,000 Total cost $65.00 $2,470,000 The Rets normally sell for $70 each Fixed manufacturing overhead is constant at $532,000 per year within the range of 23.000 through 38,000 Rets per year. Required: 1. Assume that due to a recession, Polaski Company expects to sell only 23.000 Rets through regular channels next year. A large retail chain has offered to purchase 15.000 Rets if Polaski is willing to accept a 15% discount off the regular price. There would be no sales commissions on this order thus, variable seling expenses would be slashed by 75%. However. Polaski Company would have to purchase a special machine to engrave the retail chain's name on the 15,000 units. This machine would cost $30,000 Polaski Company has no assurance that the retail chain will purchase additional units any time in the future Determine the impact on profits next year if this special order is accepted in profits 2. Refer to the original data. Assume again that Polaski Company expects to sell only 23,000 Rets through regular channels next year. The Canadian Forces would like to make a one-time-only purchase of 15,000 Rets. The Forces would pay a fixed fee of $2.30 per Ret, and in addition it would reimburse Polaski Company for all costs of production (variable and fixed) associated with the units. Since the Forces would pick up the Rets with its own trucks, there would be no variable selling expenses of any type associated with this order If Polaski Company accepts this order by how much will profits be increased or decreased for the year? in profits 3. Assume that Polaski Company expects to sell only 38.000 Rets through regular channels next year. The Canadian Forces would like to make a one-time-only purchase of 15.000 Rets: The Forces would pay a fixed fee of $2.30 per Ret, and in addition it would reimburse Polaski Company for all costs of production (variable and fixed) associated with the units. Thus accepting the Canadian Forces' order would require giving up regular sales of 15.000 Rets. If the Forces order is accepted by how much will profits be increased or decreased from what they would be if the 15.000 Rets were sold through regular channels? in profits
