Answer:
The relevant of producing the handlebar is $31 per unit.
Explanation:
The submission by Munoz's President is faulty because in calculating the cost of one unit of handlebar at $40 ,allocated facility-level costs were added at $9 per unit.This cost is not relevant for the decision at hand as it would incurred regardless of whether or not the handlebar is produced in-house.
As a result, relevant cost per unit is total cost per unit less irrelevant of $9.
That gives:$40-$9=$31
Without mincing words,$31 is the relevant cost per unit.
The relevant can alternatively be calculated as found in the attached.
