12) Melquiades is worried about his grades from the microeconomics course, according to the rules for grading, the final grade is obtained as the minimum between the grade for the midterm test (x) and the final test (y). The utility function of Melquiades will depend on the grades obtained from those two tests Now, Melquiades has researched that the average student needs to study 24 minutes an additional point in each test (tests are graded from 0 to 100) obtain a) If Melquiades has 20 hours to study for both tests (x and y), how much time would he employ for each test? Figure out the grade that Melquiades will obtain in each test and his final grade in microeconomics. Elaborate a graph. b) How much additional study time would Melquiades require to increase his final grade by 10 points. Elaborate a graph. c) Suppose the difficulty of the final test increases in such a way that now each additional point would require 26 minutes of study. What would be the total cost (in minutes)…

U.S. food markets consumers viewed beef as a normal good from 1960-1976, but viewed it as an inferior good after that point. This type of change is not abnormal, in that as average household incomes rise, preferences might change. For instance, as households move from poor to middle-class, their consumption of beef might increase. However, as households move from middle- class to upper-middle-class, they might choose to purchase more exotic foods products. Assuming you are a beef producer in 1983, what will happen if incomes continue to increase? a. The marginal cost of beef will increase. b. The marginal cost of beef will decrease. c. The demand for beef will increase. d. The demand for beef will decrease.

(a) The new PlayBox gaming consoles retail for $900 each. However, a shortage of consoles caused by manufacturing delays and parts supply issues have lead to scalpers purchasing large numbers of consoles and reselling them for a profit. Due to a manufacturing fault, the scalper incurs a 50% loss on six consoles. i) If the scalper normally makes a 40% profit on the consoles, how many consoles must they sell to make up for their loss? ii) The scalper is impatient and decides to increase their price to make up for the loss faster. What price must they resell the consoles at to make back their loss upon the sale of their fourth console at the increased price?

Technology B uses 4 workers and 2 tonnes of coal to produce 100 meters of cloth. The worker's wages cost $10 and coal costs $5. We have previously calculated that the total cost of production is $50 and that the vertical intercept of the isocost line is 10.If there was a technology that used 1 more worker, how much would it have to decrease the coal required in order to cost the same? (Note: this is the absolute value of the slope of the isocost line.)
