(1) If the marginal cost of production is greater than the average cost, in what direction must the average cost be changing, if any?
(4) If the fixed cost of Alex’s engraving business is $100, and the variable cost of each engraving job is $20, what is the marginal cost of the second engraving job?
1) If the marginal cost of production is greater than the average cost, in what direction must the average cost be changing, if any?
Solution: Average cost would be rising
Explanation: When the average variable cost is increasing, then the last unit produced is adding more to total variable cost than the previous units thus marginal cost of production is greater than the average cost
2) If the average variable cost of producing 5 costumes in Kira’s Costume Shop is $50, and the fixed cost of the shop is $100, what is the total cost for 5 costumes?
Solution: 350
Explanation:
AVC = TVC / No of units
50 = TVC / 5
TVC = 250
Total cost = TVC + TFC = 250 + 100 = 350
3) Which of the following expenses would be a fixed cost for a party cruise ship?
Solution: The port docking fee
Explanation: The port docking fee will remain constant thus is a fixed expense
4) If the fixed cost of Alex's engraving business is $100, and the variable cost of each engraving job is $20, what is the marginal cost of the second engraving job?
Solution: $20
Explanation: Marginal cost equals change in total variable cost divided by the change in quantity, thus $20 /1 = 20
