Answer:
total contribution margin = $579,000
operating income = $277,000
average contribution margin ratio = 48.33%
break even sales volume = $624,870.68
Explanation:
Product A: Sales $466,000; Contribution Margin Ratio 30%
Product B: Sales $732,000; Contribution Margin Ratio 60%
Mix's fixed expenses are $302,000
total contribution margin = ($466,000 x 30%) + ($732,000 x 60%) = $139,800 + $439,200 = $579,000
weighted contribution margin = (466/1198 x 30%) + (732/1198 x 60%) = 11.67% + 36.66% = 48.33%
break even sales volume = $302,000 / 48.33% = $624,870.68
operating income = $579,000 - $302,000 = $277,000
