Answer:
Results are below.
Step-by-step explanation:
Giving the following information:
Make in-house:
Selling price= $13.5
Unitary variable cost= $10
Purchase:
Selling price= $11.9
Purchase price= $5
Unitary variable cost= $5
To determine which option is best, we need to determine the unitary contribution margin. The option that provides the higher unitary contribution margin, is the better choice.
Unitary contribution margin= selling price - unitary variable cost
Make in-house:
Unitary contribution margin= 13.5 - 10
Unitary contribution margin= $3.5
Buy:
Unitary contribution margin= 11.9 - 5 - 5
Unitary contribution margin= $1.9
It is more profitable to make in-house.
