KAMVA 489 Time Remaining: 02:54:13 Hide Time Remaining A Suppose the weighted marginal utility for two goods, x and y, at a position of consumer equilibrium is 70. If the price of good x is R10 and the relevant marginal utility for y is 140, what is the price of good y and the relevant marginal utility for good x? A. The price of y = R70; the marginal utility for x = 70 %3D B. The price of y = R2; the marginal utility for x = 700 C. The price of y = R10; the marginal utility for x = 700 D. The price of y = R2; the marginal utility for x = 140 E. The price of y = R140; the marginal utility for x = 70 Reset Selection |54 II

5. Janice consumes two goods, X and Y. Janice has a utility function given by the expression: U=4X05Y05 and current prices of X and Y are $25 and $50, respectively. Janice currently has an income of 750 unit per time period. a. Write an expression for Janice's budget constraint. b. Calculate the marginal rate of substitution of X for Y. (horizontal line X, vertical line Y). c. Calculate the values of X and Y that will maximize utility. d. Graph your answers (budget line, indifference curve)

Can you help me answer this macroeconomics theory question

Why does a change in income cause a parallel shift in the budget constraint?

Recent research confirms that the demand for cigarettes is not only inelastic, but it also indicates that smokers with incomes in the lower half of all incomes respond to a given price increase by reducing their purchases by amounts that are more than four times as large as the purchase reductions made by smokers in the upper half of all incomes. How can the income and substitution effects of a price change help explain this finding?

Consider the two questions about utility. The table refers to the first question only. Tod loves to travel, and he takes several river cruises per year. The table contains information about the utility Tod gets from the river cruises. Number of river cruises Total utility Marginal utility 0 0   1 12 12 2 20 8 3 25 5 From this information, it can be concluded that the number of river cruises Tod takes is indeterminable without knowing Tod’s income or the price of the cruises. that total utility is maximized when Tod takes one river cruise. that Tod will take two river cruises. that Tod will take three river cruises. Suppose that Jim has $4 to spend on a snack and that the only thing available is tea and scones. Jim’s marginal utility of the first cup of tea is 30 and his marginal utility of the second cup of tea is 20. Each cup of tea costs $1. Jim’s marginal utility of the first scone is 80 and his marginal utility of the second scone is 60. Each scone costs…
