Answer:
Effect on income= $8,600 increase
Step-by-step explanation:
Giving the following information:
Unitary variable cost= 12 + 1= $13
Units sold= 4,300
Selling price= $15
Because it is a special offer, and there is unused capacity, we will not take into account the fixed costs.
Effect on income= units sold*unitary contribution margin
Effect on income= 4,300*(15 - 13)
Effect on income= $8,600 increase
