8. A consumer bas utility function u(z, y) = VIy, for two goods, X and Y, where c is some positive constant. Here, z> 0 denotes the amount of X consumed and y >0 the amount of Y comsumed. Each unit of X costs 1 dollar and each unit of Y costs 1 dollar, and the consumer has a budget for X and Y of M dollars. Use the Lagrange multiplier method to find the quantities r of X and y of Y the consumer will consume in order to maximise his utility subject to the budget constraint. (Your answers will depend on c and M.) Find the corresponding value, A, of the Lagrange multiplier. Suppose that V = u(x, y") is the maximum achievable utility. Find an explicit expression for V in terms of c and M, and verify that OM = 1.

Statement You can select the object to see the slope. Your score depends on the order in which you plot the points. If you plot one point incorrectly and the others correctly, you will receive partial credit for that object. You can adjust the position of the object on the graph without changing its shape by selecting it in between the marked points and moving it around the graph. Connected Points 000 0 Curves 00 0

For each of the following scenarios, begin by assuming that all demand factors are set to their original values and Oceans is charging $350 per room per night. If average household income increases by 20%, from $50,000 to $60,000 per year, the quantity of rooms demanded at the Oceans from rooms per night to rooms per night. Therefore, the income elasticity of demand is. , meaning that hotel rooms at the Oceans are If the price of an airline ticket from MSY to ACY were to increase by 10%, from $200 to $220 roundtrip, while all other demand factors remain at their initial values,…

:= 1:36 MicrolnternationalProject 5G 49 Done International Aspect of Project Homework Below is an except pasted from a semester project for this course (broken into two pieces). Your task is to respond to this prompt and to cite at least one source. For this assignment, the source may be scholarly or from a periodical. Your source should be documented as a reference using APA style. Be sure to respond to the prompt using concepts from our course. You may use models to illustrate your points. 1. American solar farms receive billions of dollars in taxpayer subsidies each year. These subsidies allow them to substitute grain production for energy production. How do U.S. solar farm subsidies hurt or benefit Mexican farmers? 2. What does this imply for U.S. food production independence? What could be done to address this problem, and would the solution be effective? Notice, having a positive effect, a negative effect or no net-effect is a possibility on Mexican farmers. Whatever your answer,…
choices for 1 and 2 are its either "variable" or "fixed" please also do the rest of the questions and graph thank you!
