Question
Suppose that Apple's short-term total cost function is given by
TC25+5Q, where Q is the quantity produced. Which of the
following is correct about its short-term cost?
○ Average fixed costs are constant at all levels of production.
○ When production exceeds a certain level, marginal cost exceeds
average cost.
○ As production increases, marginal cost increases.
○ At all levels of production, average variable cost and marginal cost are
equal.
○ The average total cost curve is U-shaped.
