Final answer:
To determine whether Bradley should accept the Army's offer to buy 10,000 windows for $12.00 each, we calculate the additional contribution margin. The additional contribution margin is $30,000, so Bradley should accept the offer.
Step-by-step explanation:
To determine whether Bradley should accept the Army's offer to buy 10,000 windows for $12.00 each, we need to calculate the additional contribution margin. The contribution margin is the selling price minus the variable costs per unit. In this case, the selling price is $12.00 and the variable costs per unit are $9.00 (Direct Materials + Direct Labor + Variable factory oh). Therefore, the contribution margin per unit is $12.00 - $9.00 = $3.00.
To calculate the additional contribution margin, we multiply the contribution margin per unit by the number of units offered by the Army. $3.00 x 10,000 units = $30,000.
Since the additional contribution margin is positive ($30,000), Bradley should accept the offer because it will realize $30,000 in additional contribution margin.
