Cost Accounting Question:

When a fixed cost remains constant in total, the fixed cost per unit of output or input will change inversely with the change in the quantity of output or input. For instance, if the rent of the production facility is fixed at $120,000 per year and there are 30,000 machine hours of good output during the year, the rent will be $4 ($120,000/30,000) per machine hour. If there are 40,000 machine hours during the year, the rent will be $3 ($120,000/40,000) per machine hour.
