For 8 units of output, average fixed cost is $12.50 and average variable cost is $81.25. The total cost at this output level is ____________.

If you know that when a firm produces 10 units of output, total cost is $1,030 and average fixed cost is $10, then total variable cost isMultiple Choice$104.$930.$1,040.$1,130.

Assume that in the short run, a firm which is producing 100 units of output has average total costs of $200 and average variable costs of $150. The firm's total fixed costs are:Group of answer choices$500.$0.50.$50 .$5000.

A firm has fixed costs of $400, average total costs of $3 and average variable costs of $2.50. The output of the firm is _____________.
