If a firm produces 20 units of output and incurs a total cost of $1000, and the variable cost is $700, calculate the firm's average fixed cost of production if it expands output to 25 units.

To calculate the average fixed cost, we first need to calculate the total fixed cost.

Total cost = Fixed cost + Variable cost

We know that when the firm produced 20 units, the total cost was $1000 and the variable cost was $700.

$1000 = Fixed cost + $700

Fixed cost = $300

So, when the firm produces 20 units, the fixed cost is $300.

To calculate the average fixed cost, we divide the fixed cost by the level of output:

Average fixed cost = Fixed cost / Output

When the firm expands output to 25 units, the fixed cost remains the same ($300).

Therefore, the average fixed cost of production when the firm expands output to 25 units is:

Average fixed cost = $300 / 25 units = $12

Therefore, the best choice is C, $12.
