If the price of a pair of shoes is $20 per pair and the price of a shirt is $15 each, which of the following combinations is unaffordable to the consumer?

2. Pam is rich and at this high income level, her demand for good X is independent of income and given by X*=37.2- 3 px/py where px and py denote respectively the price of good X and the price of good Y. Assuming the price of good Y is equal to 1, find Pam's compensating variation if the price of good X rises from 2 to 3.4 dollars.
Suppose there is a single commodity that absorbs all of a consumer's income. a. What is the consumer's price elasticity of demand for the commodity? b. What is the consumer income elasticity of demand for the commodity?
Denote the consumption of food by x and the consumption of all other goods by y. The demand for food as a function of prices and income is given by: Qx(px,py,W)=5W/8px. Suppose that W=100, px=3, and py=5. The change in consumption of food that is caused by a 2% increase in W is approximately: An increase of 2% in demand of y. There is no change. A decrease of 2% in demand of y. A decrease of 2% in demand of x. An increase of 2% in demand of x.
Problem 2 The demand-function for a given consumer good (A) is given as: ?_a=1400−4?_?−2?_?−0.005_? Where PA = 200 USD is the price for good A, PB = 50 USD is the price for good B, and I = 20,000 USD is the disposable income. Question 2.1 Provide examples of three more factors that influence demand of consumer good A, besides the ones presented in the equation above. Briefly explain why and how they would influence demand. Question 2.2. Find price point elasticity for good A and provide an economic interpretation. Question 2.3. Find cross price elasticity between goods A and B and provide an economic interpretation.
6. When a good is normal:(a) An increase in income raises consumption at each price, so the demand curve shifts tothe left(b) An increase in income raises consumption at each price, so the demand curve shifts tothe right(c) A decrease in income lowers consumption at each price, so the demand curve shifts tothe right(d) An increase in income lowers consumption at each price, so the demand curve shiftsto the left.
2. The demand for good X is given by:d= 6,000 - 0.5Px - Py +9Pz + 0.1MQxResearch shows that the prices of related goods are given by Py = $6,500 and Pz = $100, while theaverage income of individuals consuming this product is M = $70,000.a. Indicate whether goods Y and Z are substitutes or complements for good X.b. Is X an inferior or normal good?c. How many units of good X will be purchased when Px = $5,230?d. Determine the demand function and inverse demand function for good X. Graph the demand curve forgood X.
E1 Suppose the Federal Government issues $100 worth of food stamps to everyone in your city. These stamps are coupons that can be exchanged for $100 worth of food at the grocery store and they can be used only by the person to whom they are issued. Draw your budgetline between “food’ and “all other goods” both before and after the food stamps are issued. Assume the price of food = price of “all other goods” = $1.00 and the individual’s initial income is $200.
