Answer:
$4.15 per unit
Step-by-step explanation:
The computation of the relevant cost of manufacturing the motor is shown below:
Relevant cost per unit = Direct material per unit + direct labor per unit + variable overhead per unit
= $1.75 + $1.65 + $0.75
= $4.15 per unit
For reaching the decision, we simply added the direct material per unit, direct labor per unit and variable overhead per unit so that the correct answer could arrive
