Answer:
Instructions are below.
Step-by-step explanation:
Giving the following information:
Units= 35,000
Production costs:
Direct materials $9.40
Direct labor $8.40
Variable manufacturing overhead $3.40
The price offered to SP Corporation for this motor is $23.65.
We will not take into account the fixed costs, they remain constant in both options.
Make in-house:
Total cost= 35,000*(9.4 + 8.4 + 3.4)= $742,000
Buy:
Total cost= 35,000*23.65= $827,750
It is cheaper to continue making the parts.
