Answer:
$396
Step-by-step explanation:
Calculation for the contribution margin per unit sold for recurring sales
Using this formula
Contribution margin per unit = Normal Selling price per unit - (Direct material +Direct labor+Variable factory overhead)-Variable selling & administrative costs
Let plug in the formula
Contribution margin per unit = $750 - ($120+ $150 + $60) - $24
Contribution margin per unit = $750 - $330 - $24
Contribution margin per unit= $396
Therefore the contribution margin per unit sold for recurring sales will be $396
