Columns 1 through 4 of the accompanying table show the marginal utility, measured in utils, that Ricardo would get by purchasing various amounts of products A, B, C, and D. Column 5 shows the marginal utility Ricardo gets from saving. Assume that the prices of A, B, C, and D are $18, $6, $4, and $24, respectively, and that Ricardo has an income of $105. What quantities of A, B, C, and D will Ricardo purchase in maximizing his utility? How many dollars will Ricardo choose to save? Check your answers by substituting them into the algebraic statement of the utility‑maximizing rule. In other words, show it works when using this rule.

. Suppose that initially, bread is $2 per loaf,and cake is $2 per slice. Marie Antoinettehas $18 to spend on these items each week.At this income and those prices, Marie consumes 5 loaves of bread and 4 slices of cake.Then, the price of bread DECREASES to$1 per loaf. (The price of cake is still $2.)IF Marie’s budget had also fallen to $13so that she could still just afford her original bundle, she WOULD choose to spendthose $13 on 7 loaves of bread and 3 slicesof cake.But since Marie still has her original $18budget, she actually chooses to buy 4loaves of bread and 7 slices of cake afterthe price change.When the price of bread fell from $2 to $1,what was the substitution effect on Marie’sdemand for bread?

Suppose that, from an initial individual consumer equilibrium position in the indifference curve-budget line diagram, the prices of both goods rise by 10 percent. What happens to the position and slope of the budget line? Why does the consumer’s level of satisfaction from a given money income fall? Illustrate and explain. Would it be acceptable for an economist to say that the level of satisfaction of the consumer fell by exactly 10 percent? Why or why not?

please only do: if you can teach explain each partc: what does it mean? can you show graphs: For these to be optimal choices with such preferences, the indifference curve through a must lie entirely on or above the budget line associated with (p, w), and simi- larly for r' for the budget line associated with (p', w'). how do you know this:Because each of these bundles lies below the other budget line, this implies that the indifference curves must cross, which is impossible. can you show graphs: note that (3,1) is a conver combination of x and x', so for conver preferences must be weakly preferred to x (the less preferred bundle between a and a'). But then the bundle (3,5/3) must be strictly preferred z, contradicting that is optimal given the initial budget set
Lexicographic preferences describe preferences where an economic agent prefers any amount of one good (X) to any amount of another (Y). SpeciÖcally, if o§ered several bundles of goods, the agent will choose the bundle that o§ers the most X, no matter how much Y there is. Only when there is a tie between bundles with regard to the number of units of X will the agent start comparing the number of units of Y across bundles. Show that Lexicographic preferences are transitive
True or false with reasoning 1)_______When an extra glass of wine is consumed, the total utility gained from the consumption changes by an amount of the marginal utility of all goods consumed. 2)_______Suppose that you consume two goods A and B, and that MUA/PA = 2 and MUB/PB = 4. With a given income and prices, the consumer will purchase more of good A and less of good B. 3)_______If you consume two goods, X and Y, and MUX > MUY, then you are willing to pay more for good X than for good Y.
Q1 please help me quickly!! Your budget is $200. The price of good 1 (x1) is $4 per unit, and that of good 2 (x2) is $3 per unit. Then, the equation for your budget line can be written as O 5x1 + 3x2 = 200 ◎ 4x1 + 3x2 = 200 ◎ 4x1+ 4x2 = 200 O 5x1 + 3×2 = 195

For well behaved preferences the income effect is positive.O. For well behaved preferences the substitution effect is non positive.O. if the demand foro good increases when income then the demand for that good must decrease when its price increases.O. A Giffen good cannot be explained by the Slutsky-Hicks equation.
Suppose that with a budget of $100, Deborah spends $60 on sushi and $40 on bagels when sushi costs $2 per piece and bagels cost $2 per bagel. But then, after the price of bagels falls to $1 per bagel, she spends $50 on sushi and $50 on bagels. How many pieces of sushi and how many bagels did Deborah consume before the price change? At the new prices, how much money would it have cost Deborah to buy those same quantities (the ones that she consumed before the price change)? Given that it used to take Deborah’s entire $100 to buy those quantities, how big is the income effect caused by the reduction in the price of bagels?
