(1) At point A, MRS is equal to the ratio of prices.
At point A, consumer is spending all of his/her income but still there is a chance to consume on higher IC and get higher utility at the tangency between budget line and higher IC.
(2). Consumer will buy more of Y at the tangency between budget line and higher IC.
(3). Consumer maximize utility at the tangent point, occurs between budget line and IC.
So that at maximizing utility point, slope of IC (I e., MRS) and slope of budget line (i.e. Px / Py) is equal.
MRS = Px / Py
MRS = slope of budget line.
MRS= 10 / 5.
MRS = 2.
Thus, MRS will be 2 when the consumer is maximizing their utility.

This quiz works through the utility maximization problem for Martina. Let's assume Martina's preferences are given by U(X,Y) = X1/3Y2/3 and her income is equal to $500. Prices for goods X and Y are equal to PX = $4 and PY = $2. A) What is the value of Martina's marginal rate of substitution (MRS) at (X, Y) = (2, 20)? B) What is the |slope| of Martina's budget constraint? (Enter an integer) C) If Martina purchased only good X,...
can you please explain this deeply? thank you Question 7 Consider a consumer with preferences over two goods 1 and 2. Assume that the horizontal axis pertains to the amount of good 1 and the vertical axis pertains to the amount of good 2. Suppose that, given the consumption bundle r = 10 and y = 10, a consumer's MRS (marginal rate of substitution) is equal (in absolute value) to 4. The price of good 1 is $1, the price...
be found in a connect 2. Mrs. Simpson buys loaves of bread and quarts of milk each week at prices of $1 and 80 cents, respectively. At present she is buying these products in amounts such that the marginal utilities from the last units purchased of the two products are 80 and 70 utils, respectively. Is she buying the utility-maximizing combination of bread and milk? If not, how should she reallo- cate her expenditures between the two goods? LO7.2 T...
1. Megan has $50 in their budget. Given the following graph what's the MRS at her optimal consumption bundle? 2. The demand curve for airplanes is: Qc=15,000 - .2Pc - 800Pg where Qc is the quantity of airplanes, Pc is the price of airplanes and Pg is the price of gasoline. By what quantity does the demand for airplanes change if the price of gasoline goes down by $.50? a) 400 b) 800 c) -400 d) -800 e) Can’t be...
General Equilibrium: Consider an economy that can produce tacos (X) and hamburgers (Y). Let the production possibilities frontier (PPF) be Y2 = 100-4X2 (Eq. 1) or, equivalently ? = √100 − 4?2 (Eq. 2) (for positive values of tacos and hamburgers). This means that the rate of product transformation (RPT), the number of hamburgers that must be given up to get one more taco along the PPF, is − ??/?? = 4?/(√100−4?2) a. Suppose initially that the price of X...
2. Suppose that Peggy’s marginal rate of substitution of two goods (MRSXY) is greater than the relative price ratio (Px/Py) in absolute value. Assuming that a diagram of Peggy’s budget constraint reflects the quantities of good Y measured on the vertical axis and quantities of good X measured on the horizontal axis, she will Buy more of good Y and move down the budget line Buy more of good Y and move up the budget line Buy more of good...
Need this answered as soon as possible 5. General Equilibrium: Consider an economy that can produce bowls of chili (X) and hot dogs (Y). Let the production possibilities frontier (PPF) be Y = 100-4X (Eq. 1) or equivalently Y = V100 - 4X2 (Eq. 2) (for positive values of chili and hot dogs). This means that the rate of product transformation (RPT), the number of hot dogs that must be given up to get one more bowl of chili along...
1. answer it only numerical values. 2. A person has a Cobb Douglas utility function for two goods X and Y. If the price of a X increases and the budget stays the same, the utility maximizing person __________. Cannot be determined from the information will consume less of Y will only consume Y will consume less of both goods will have lower utility Sara has $40 in her budget. Given the following graph, what is the MRS of her...
