Answer:
Effect on income= $248,500 increase
Step-by-step explanation:
Because it is a special order, we will not take into account the fixed manufacturing costs and fixed selling costs.
Direct materials= $20
Direct labor= $17
Variable manufacturing overhead= $13
Variable selling expense= 12*0.25= $3
Total unitary cost= $53
Now, we can determine the effect on the income of accepting the offer:
Effect on income= 7,000*(90 - 53) - 10,500
Effect on income= $248,500 increase
