I posted this question before as well, but didn't get any help! Please help me solve this :(

2. Refer to the original data. Assume again that Polaski Company expects to sell only 25,000 Rets through regular channels next year. The Canadian Forces would like to make a one-time-only purchase of 17,000 Rets. The Forces would pay a fixed fee of $2.60 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? Net increase in profit 3. Assume that Polaski Company expects to sell only 42,000 Rets through regular channels next year. The Canadian Forces would like to make a one-time-only purchase of 17,000 Rets. The Forces would pay a fixed fee of $2.60 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 17,000 Rets. If the Forces' order is accepted, by how much will profits be increased or decreased from what they would be if the 17,000 Rets were sold through regular channels? Net decrease in profits
