Answer: 200%
Step-by-step explanation:
First find the return required.
= 10% of total assets
= 10% * 5,000,000
= $500,000
The total manufacturing costs are:
= 250,000 + 450,000
= $700,000
We need to know the amount to increase the manufacturing costs by so that it covers both the desired return and the admin costs:
= (Desired return + Admin costs) / Manufacturing costs * 100%
= (500,000 + 600,000 + 300,000) / 700,000 * 100%
= 200%
