Average variable cost: first tends to decrease, and then increase as output expands. remains unchanged as output expands. always increases as output increases. always decreases as output expands.

Which of the following is correct?   a) Total Fixed Cost = Total Cost + Total Variable Cost b) Total Cost = Total Variable Cost + Marginal Cost c) Average Fixed Cost = Average Total Cost – Average Variable Cost d) Average Total Cost = Marginal Cost + Average Fixed Cost

a) when the plant is small b) when the plant is medium-size Oc) d) e) at an output level less than q when the plant is large at an output level more than q

fixed cost is the same at each output level except when no output is produced. when a firm produces no output,there are no fix cost. true or false? explain

The fixed cost per unit is equal to: Multiple choice question. average variable cost. average total cost. average fixed cost. marginal cost.
