Questions from this subtopic
Each one with the model answer underneath.
- 1
What are fixed costs?

Costs that do not change with the level of output in the short run, such as rent, business rates, insurance and salaried staff.
- 2

- 4
A business has fixed costs of £24,000 and variable costs of £6 per unit. Calculate its total cost at an output of 4,000 units.
Model answer
Total cost is £48,000, being £24,000 of fixed costs plus £24,000 of variable costs.
- 5
A firm's total cost is £48,000 at an output of 4,000 units. Calculate its average cost per unit.
Model answer
Average cost is £12 per unit.

Why does average cost fall as output rises while fixed costs stay the same?
Model answer
The same total fixed cost is spread over a greater number of units, so fixed cost per unit falls while variable cost per unit is unchanged.
