1. Mariel runs an ice cream shop. Her short-run cost is given by 300 + is the number of ice cream cones she sells per day. + 3q where q 3000 (a) Find mathematical expressions for Mariel's marginal cost, average variable cost, and average total cost. (b) Sketch' Mariel's marginal cost, average variable cost, and average total cost. (c) Suppose the market price for ice cream cones is $3. How many ice cream cones will Mariel supply? What will her profits be? Identify your answers on the diagram and then compute the values mathematically. (d) Find the minimum market price such that Mariel will stay in business in the short-run, both on your diagram and mathematically. (e) Assume that Mariel can only run an ice cream shop of this size and in the long run must decide whether to operate or not. (In other words, assume that Mariel's LRAC curve is her short-run average total cost curve.) Identify the minimum market price such that Mariel will stay in business in the long-run on your diagram.…
Consider total cost and total revenue given in the following table: TABLE IN IMAGE Calculate profit for each quantity. How much should the firm produce to maximize profit?(ii) Calculate marginal revenue and marginal cost for each quantity. Graph them. (Hint: Put the points betweenwhole numbers. For example, the marginal cost between 2 and 3 should be graphed at 2½.) At what quantitydo these curves cross? How does this relate to your answer to part (a)?(iii) Can you tell whether this firm is in a competitive industry? If so, can you tell whether the industry is in along-run equilibrium? (8.75)

A summary of some of his costs, which are given in the local currency (the "vatu"), is shown below. Quantity (kg of galip nuts) 0 30 60 90 120 150 Total Fixed Cost TFC (vatu) 5600 5600 5600 5600 5600 5600 Total Variable Cost TVC (vatu) 0 640 1520 2640 4800 9120 If John's profit-maximising quantity is 90kg of galip nuts, what is the marginal revenue per kilogram of galip nuts at this profit maximising quantity? Answer to the nearest whole number.
1. Suppose a firm’s cost function is given by C(q) = 20 + 10q − 4q^2 + q^3(a) What is fixed cost?(b) What is variable cost?(c) Compute average cost, average fixed cost, and average variable cost, assuming q > 0.(d) Derive marginal cost.(e) Solve for the shut-down level of production, qSD. (Hint: The minimum of a well-behavedcurve can be found by setting the first derivative equal to zero.)
