【正确答案】
【答案解析】(a) Total variable costs: $ Materials 300,000 Labor ($200,000×25%) 50,000 Selling & distribution cost ($50,000×20% ) 10,000 360,000 Variable cost per unit =$360,000 / 3,000 =$120 Contribution per unit =Selling price - Variable cost =$300 -$120 =$180 Breakeven point (in units) = Fixed cost / Contribution per unit = ($200,000×75% +$50,000×80% +$170,000)/$180 = $360,000/$180 = 2,000 units Breakeven point (dollars sales) = Breakeven units × Selling price per unit = 2,000×$300 = $600,000 (b) the contribution to sales ratio = $180 / $300×100% = 60% (c) the margin of safety = (Current sales - breakeven sales) / Current sales×100% = (3,000×$300-$600,000)/$900,000×100% = 33.3%
