Answer:
18%
Step-by-step explanation:
The computation of the percentage of the total fixed costs per unit is shown below:
= Total fixed cost ÷ Total cost
where,
Total fixed cost = Fixed manufacturing overhead + administrative salaries
= $12 + $24
= $36
And, the total cost is $200
So, the percentage of the total fixed costs per unit is
= $36 ÷ 200
= 0.18 or 18%
