Suppose that Kari and Hector are the only two consumers in the market for pizza slices. Assuming that both Kari and Hector are consuming some pizza each, which of the following functions describes the relevant portion of the market demand curve? Choose one: O A.

Q %3D 2,500 — (4 + 10)Р O Ouppose two individuals (Cindy and Elicia) each have 12 hours of labor to devote to producing either roti (X) or fry rice (Y). Cindy’s demand for X and Y is given by: XC = 6/PX and YC = 6/PY, whereas Elicia’s demands are given by, XE = 8/PX andYE = 4/PY. The individuals do not care whether they produce X or Y and the production function for each good is given by X = 3L; Y = 4L where L is the total labor devoted to production of each good. The equation for the frontier is given by X/3 + Y/4 = 24. Which is the price ratio, Px/Py?From the information given in the preceding question (in which Ming views X and Y as perfect complements), we know that O when the price of Y increases, Ming's demand curve for X shifts in. O when the price of Y increases, Ming's demand curve for X shifts out. when the price of X increases, Ming's demand curve for X shifts out. O Ming's demand curve for X is a horizontal line. O Ming's demand curve for X is a vertical line.
- Be fast Suppose there are three (3) consumers in a market for bottles of perfume; Mutumbu, Jasanu and Julius The individual demand for perfumes for each of these consumers is given as 10 bottles for Mutumbu, 15 bottles for Jasanu and 25 bottles for Julius at $60 per bottle for perfume. Thus, the market demand for perfumes if the market price is $60 is: (a)40 bottles (b)60 bottles (c)80 bottles (d) None of the aboveSuppose there are two firms selling protein bars. Firm 1 sells 'AggieBars' with 10 grams of protein and firm 2 sells 'DavisBars' with 20 grams of protein. Consumers are distributed uniformly over their preferences for grams of protein between 10 and 20. Suppose firm 1 sells AggieBars for $2 and firm 2 sells DavisBars for $3. The 'cost to consumers of deviating from their optimal amount of protein is $0.20 per gram. a. What protein content does the marginal consumer (the consumer who is indifferent between AggieBars and DavisBars) prefer? The equation for finding the marginal consumer (when the range of product attribute values is 10) is V - p1 - tx m = V – p2 – t(10 – x m) 4 b. How would the proportion of consumers buying each product change if the cost to deviation from one's optimal amount of protein increased (was greater than $0.20 per gram)?Suppose that Paolo and Sharon are the only consumers of ice cream cones in a particular market. The following table shows their monthly demand schedules: Price Paolo’s Quantity Demanded Sharon’s Quantity Demanded (Dollars per cone) (Cones) (Cones) 1 8 16 2 5 12 3 3 8 4 1 6 5 0 4 On the following graph, plot Paolo’s demand for ice cream cones using the green points (triangle symbol). Next, plot Sharon’s demand for ice cream cones using the purple points (diamond symbol). Finally, plot the market demand for ice cream cones using the blue points (circle symbol). Note: Line segments will automatically connect the points. Remember to plot from left to right.

Explain 2. Graphically show the effect of an increase in price of Coca Cola on the demand of PepsiCola 3. Assume a budget line is drawn for two commodities: X on the x-axis and Y on the y-axis. Ifthe income of the consumer is 120 Birr, the y-intercept is 3, and the slope of the budget lineis -0.5 then determined the price of commodity…Carol and Bob both consume the same goods in an economy of pure exchange. Carol is initially endowed with 9 units of good 1 and 6 units of good 2. Bob is initially endowed with 18 units of good 1 and 3 units of good 2. They both have the utility function U(x₁, x₂) = 1/3 2/3 x1³x2³. If we set good 1 as the numeraire (so that p. = $1), what will the equilibrium price of good 2 be?
