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?

Calculate total costs at 4 units of output.  Do not put a dollar sign in your answer.  (The 6 columns are Quantity, Total Fixed Cost, Total Variable Cost, Total Cost, Average Total Cost, and Marginal Cost.  The Quantity and Total Variable Cost columns have been filled in along with the first row for Total Fixed Cost.  Average Total Costs and Marginal Costs are not calculated at a quantity of 0.) Quantity Total Fixed Cost Total Variable Cost Total Cost Average Total Cost Marginal Cost 0 15 0   XXXXX XXXXX 1   25       2   40       3   50       4   55       5   65       Calculate average total costs at 2 units of output.   Calculate average total cost at 5 units of output.   Calculate marginal cost at 4 units of output (moving from 3 units to 4 units).   Can you tell if this is the short run or long run?    Can you tell at which level of output profits will be maximized?

15 3. Jane's Juice Bar has the following cost schedules: Quantity 0 vats of juice $0 1 10 12 25 3 45 4 70 100 135 10 1 12 13 14 15 Variable cost Total cost $30 40 55 75 100 130 165 Calculate average variable cost, average total cost, and marginal cost for each quantity. Put these numbers in the table below. Quantity Average variable cost Average total cost Marginal cost a. b. Graph all three curves (average variable cost, average total cost and marginal cost) using Excel or a piece of grid paper. Attach the graph to this assignment. What is the relationship between the marginal-cost curve and the average total cost curve? Between the marginal cost curve and the average variable cost curve? Explain

I already filled out the table, but I don't understand how to answer 3. a, b, and c.
