Answer:
The correct answer is:
$19,000 decrease (a)
Explanation:
To calculate this, we have to calculate the total cost involved, when the product was manufactured and when it was purchased and calculate the difference in cost.
Note also that when calculating cost for manufacturing, you do not add fixed overhead costs because they are not costs associated with the direct manufacture of a product, rather, they are costs associated with the day to day running of the business, example here may be the electricity used in the factory.
Total manufacturing cost ($);
Direct materials = 150,000
Direct labor = 170,000
variable overhead = 70,000
Total = $390,000
Total purchase cost ($)
1 component = $14
∴ 30,000 components = 30,000 × 14 = 420,000
if the facilities are rented out for $11,000, Damon could use the money for the purchase too, therefore effective cost for purchase;
= 420,000 - 11, 0000 = $409,000.
Now finding the difference between the two costs;
cost of purchase = $ 409,000
Cost of manufacture = $ 390,000
difference = $19,000
since the cost of purchase of the components is more than the cost of manufacturing by $19,000, it means that the operating profits will reduce by $19,000 if Damon chooses to purchase the components
