A business firm
produces and sells specialty cakes. Last year, the firm produced
12,000 cakes and sold each cake for $20. In producing the 12,000
cakes, it incurred variable costs of $150,000 and a total cost of
$183,000. Which of the following statements is (are) correct?
(x) The firm’s economic profit for the year was more than $51,250
but less than $54,375.
(y) Fixed costs amounted to $33,000 and average fixed costs are
$2.75 per unit for 12,000 cakes.
(z) In producing the 12,000 specialty cakes, the firm’s average
variable cost was more than $12.25 per cake and its average total
cost was less than $15.75 per cake.

Which of the following
statements is (are) correct?
(x) If marginal cost is $10 and rising, average variable cost could
be either greater than or less than $10.
(y) If you know the average variable cost of 75 units then you have
sufficient information to calculate the marginal cost of the 75th
unit.
(z) If you know the average fixed cost of 600 units then you have
sufficient information to calculate the average fixed cost of 400
units.

Answer-1 The correct option is B.) (x) and (y) only
Long-run average total cost curves are often U-shaped because of
increasing specialization of workers
at low levels of production and increasing coordination problems at
high levels of production.
Answer-2 The correct option is E.) (y) only
Total Revenue= Price * Quantity
= 20 * 12000
= $2,40,000
Variable costs = $150,000
Total cost = $183,000.
Economic Profit= Total Revenue- Total Cost
= 240000- 183000
= 57,000
Fixed cost = Total cost - Variable cost
= 183,000- 150,000
=33,000
Average fixed cost = Fixed cost/Quantity
= 33,000/12,000
= 2.75
Average variable cost = Variable cost/Quantity
= 150,000/12,000
= 12.5
Average total cost = Total cost/Quantity
= 183,000/12,000
= 15.25
Answer-3 The correct option is C. )(x) and (z) only
(y) is not correct because by information of average variable cost of 75 units we cannot calculate calculate the marginal cost of the 75th unit. We need to have information of average variable cost of 74 units.

which of the following statements is (are) correct? (x) Average variable cost equals variable costs divided by quantity produced. (y) Marginal cost equals the change in variable costs divided by the change in quantity produced. (z) If you find the difference between average total cost and average variable cost and then multiply that value by the specified quantity then the resulting value is the amount of fixed costs. A. (x), (y) and (z) B. (x) and (y) only C. (x)...
Which of the following statements is (are) correct? (x) The average variable cost curve declines as quantity increases because variable costs always decrease as output increases. (y) The average variable cost curve and average total cost curve will eventually intersect as output increases because average fixed cost eventually becomes negative. (z) The marginal cost curve crosses the average total cost curve at the efficient scale, which occurs at the minimum point on the average total cost curve. A. (x), (y)...

QUESTION 13 Every point on the long-run average cost curve is O on a short-run marginal cost curve. also a minimum point on a short-run average cost curve. O on a short-run average total cost curve. O on a short-run average variable cost curve. QUESTION 14 If total costs are $50,000 when 1000 units are produced, and total costs are $50,100 when 1001 units are produced, we can conclude that O average variable costs are $100. o marginal costs are...
