想問這一題如何計算🥹

3. Consider a perfectly competitive firm with the following short-run total costs: SRTC = 150 + 2q². The corresponding short-run marginal cost is given by: SRMC = 4q. a. If the market price is $80, how much output will the firm produce? b. What will the firm's profits be at a price of $80? c. Find the quantity of output for which marginal cost equals average variable cost. What does this information tell you about this firm's decision about whether to shut down in the short run rather than produce a positive quantity of output?

1. Any of you who have listened to children tell stories will recognize that, unlike adults, they tend to recall stories as a sequence of actions rather than as an overall plot. Their descriptions of a movie are filled with the phrase "and then...." An experimenter with supreme patience asked 50 children to tell her about a given movie. Among other variables, she counted the number of "and then..." statements, which is the dependent variable. The data follow: 18 15 22 19 18 17 18 20 17 12 16 16 17 21 23 18 20 21 20 20 15 18 17 19 20 23 22 10 17 19 19 21 20 18 18 24 11 19 31 16 17 15 19 20 18 18 40 18 19 16 簡單翻譯:心理學家請小孩描述電影情節,並記錄他們使用「然後」的次數,50 位小孩的次數 如上。

Problem-Based Learning Cost of Production Scenario 1: Preparation for New Business Shawn wants to start a new business by selling watermelon juice. In particular, he withdrew $500,000 of his saving from the commercial bank to cover his expense (for new business). Below is a list of costs associated with the production inputs: Table 1 Items Rent (Location) Wage Ingredient Machine Rental Electricity Fee Advertisement Fee Straw Table Rental Plastic Cup Plastic Cup Lids Plastic Bag Decoration Service Fee Cost $2,000 per day $160 per hour $6 per cup of juice $14 per day $21 per hour $73 per day $0.12 per straw $5.5 per day $0.7 per cup $0.1 per lid $0.5 per bag $35 per day Problem 1: Do we take into consideration the investment funds, Shawn's deposit ($500,000), when we compute the economic cost? Why? Problem 2: In Economics, we generally divide the production inputs into two categories, fixed input and variable input. Could you please categorize the production inputs, listed in Table 1, into fixed and variable inputs?
