Answer:
d. Income would increase by $25000.
Step-by-step explanation:
Concord Corporation received a special order to sell 1,000 units at $125 each.
Incremental Sales Revenue = 1,000 * $125
Incremental Sales Revenue = $125,000
Variable Cost per unit = $100
Fixed manufacturing cost = $480,000
To produce required additional units, there will be no change in fixed manufacturing costs. So, cost to produce additional units will change on account of variable manufacturing cost only.
Incremental Cost = $100 * 1,000
Incremental Cost = $100,000
Incremental Net Income = Incremental Sales Revenue - Incremental Cost
Incremental Net Income = $125,000 - $100,000
Incremental Net Income = $25,000
