Answer:
The company would incur $ 30,000 additional costs if it buys the switches.
No, the company should make switches in order to avoid additional costs even if the income is increased.
Step-by-step explanation:
Wilma Company
 Make Buy Net Income 
 ( increase / decrease)
Direct Material $30,000 $30,000 
 Direct Labor $42,000 $42,000 
 Variable Overhead $45,000 $45,000 
Fixed Overhead $60,000 $ 45000 $ 15000
Purchase Price (2.7 *60,000) 
 162,000 ( 162,000)
Total $177,000 $ 207,000 (30,000)
The company should make the switches because it costs more to buy rather than to make.
The company would incur $ 30,000 additional costs if it buys the switches.
No because even if the income is increased the better option would be to make switches to save the additional costs.
