Question 1 Suppose there is only one supplier in the market of product X. The following table shows partial information of product X and the supplier's cost Price Quantity 0 Marginal Cost $1,700 1,500 1,400 1,300 1,200 1,100 1,000 1 380 2 390 410 430 5 460 500 7 900 550 800 610 700 770 600 10 790 A. Determine the supplier's profit-maximizing output quantity. Explain your answer. B. At what price should the supplier charge to maximize its profit? Explain your answer. C. Suppose at the profit-maximizing output quantity you have determined in part A, the average variable cost is $428.33 and the average total cost is $628.33 Calculate the total profit at the profit-maximizing output quantity

Your task is to show what the profit of this firm might look like using a key economics diagram. To make graphing easier, we will consider the price of the Ozempic drug for the middle-income country Bangladesh, which is $38 (assumed the profit-maximising price). For this task, you will be required to illustrate and explain to a typical first-year undergrad student who has no economics background the profit the firm makes at $38 per month, and what has happened to profit (producer surplus), markup, consumer surplus and the output if the price was reduced from $38 to $10 per month.

I pretty sure I got the first part right. I am struggling with bottom parts.

Suppose that you are the marketing manager of Citruscity, the only producer of grapefruits in the imaginary economy of Blockburg. As a monopolist, Citruscity's objective is to maximize its profit, so it is up to you devise a way to increase profits through price discrimination. As a former economics student, you know that many firms successfully practice price discrimination by separating their market into two identifiable types of consumers-what economists call third-degree price discrimination. Examples of this include student discounts, senior citizen discounts, and ladies' night discounts. After doing some research, you conclude that the demand for grapefruits varies greatly between consumers who clip coupons and those who do not. The following graphs show the overall dailly demand and marginal revenue (MR) for a pound of grapefruits for each group of consumers and the marginal cost (MC) for producing a pound of grapefruits. Assume that fixed costs are equal to zero. Note: You will…
