Which linear inequality is described by the graph below?51-5-5x<2Bx< 2C y<2Dy<2 An airline offers economy and business class tickets. For the airline to be profitable, it must sell a minimum of 25 businessclass tickets and a minimum of 40 economy tickets. The airline makes a profit of P3500 for each economy ticket andP6000 for each business class ticket.Let x and y be the number of economy and business class tickets, respectively. Which of the following is not a constraint inthe problem?Ax20By > 25x> 40D3500x + 6000y

Investment A woman invests $360,000 in three different mutual funds. One averages 12% per year,and another averages 16% per year. A third fundaverages 8% per year, and because it has much lessrisk, she invests twice as much in it as in the sum ofthe other two funds. To realize an annual return of$35,200, how much should she invest in each fund?

with the information given draw a graph, On the x-axis, you would have the number of units sold (from 0 to 800,000 in increments of 100, 000) and on the y-axis, you would have the dollar amount (from 0 to $3,200,000 in increments of $ 400,000). Draw a line from the origin with a slope equal to the variable cost per unit ($2.5) to represent total variable costs. Draw a horizontal line at $600,000 to represent total fixed costs. The sum of these two lines gives the total cost line. Draw another line from the origin with a slope equal to the selling price per unit ($4) to represent total sales. The point where the total sales line intersects the total cost line
Suppose X1 and X2 are defined as: X1 =number of tables to produce, X2 =number of chairs to produce. Answer the following questions: (a) Write an expression representing total number of tables and chairs to be produced in terms of X1 and X2. (b) Suppose a table generates $28 of profit, and a chair generates $24 of profit. What is the expression representing the total profit of X1 tables and X2 chairs? (c) Suppose a table takes 3.3 hours of carpentry and 2.7 hours of painting. What is the expression representing total number of painting hours to be used for producing X1 tables? (d) Suppose a table takes 3 hours of carpentry, a chair takes 2 hours of carpentry, and there are 400 hours of carpentry available. Use a constraint to represent “The total carpentry hours to be used should be no more than the available carpentry hours.” (e) Use a constraint to represent “At least 34 chairs must be produced”; (f) Use a constraint to represent “No more than 380 chairs will be produced.” (g) Use a…
Consider a cheap talk game in which Nature chooses the sender’s type andthere are three feasible types: x, y, and z, which occur with probability 1/4, 1/4,and 1/2, respectively. The sender learns her type and then chooses one of fourpossible messages: m1, m2, m3, or m4. The receiver observes the sender’smessage and chooses one of three actions: a, b, or c. The payoffs are shown in the table below. a. Suppose the sender’s strategy is as follows: (1) if the type is x, thenchoose message m1, and (2) if the type is y or z, then choose messagem2. The receiver’s strategy is the following: (1) if the message is m1,then choose action a; (2) if the message is m2, then choose action b;and (3) if the message is m3 or m4, then choose action a. For appropriatelyspecified beliefs for the receiver, show that this strategy pair is aperfect Bayes–Nash equilibrium.b. Find a separating perfect Bayes–Nash equilibrium.
Company A's stock sells for $142 a share and has a 3-year average annual return of $27 per share. The beta value, a measure of risk, is 0.38. Company B sells for $149 a share and has a 3-year average annual return of $61 a share. The beta value is 1.23. Tori wants to spend no more than $12000 investing in these two stocks, but she wants to obtain at least $3000 in annual revenue. Tori also wants to minimize the risk, that is, the beta value. Determine how many shares of each stock Tori should buy.
Consider a buying firm and a supplier negotiating terms for a contract. Suppose the Marginal Benefit to the buying firm of additional contract provisions in a contract (x) to the firm is: MB = 20,000 – 400x. Suppose the Marginal Cost to the buying firm of additional contract provision to the firm is: MC = 100x. What is the optimal number of contract provisions? Reconsider the previous question. If the maximum value (or price) of the contract that the buying firm is willing to pay for is $3,000, what would you expect the firm to do? a) Use the spot market b) Vertically integrate c) Continue to contract d) engage in holdup
