Suppose a demand curve for x is given by Q, = 90 – 2P, + 2P, - 5M, where Q, is the quantity demanded of x, P, its price, P, the price of some other good y, and M represents the demander's income. a. Is xa normal good or an inferior good? b. What is Q, when P,= 5,: P, = 2; M =50? c. What is the own price elasticity of Q. when the price of x goes up from 5 to 6 (assume P, = 2; M =50)?

Timmy is selling his toy dinos again. The consumer demand curve for thedinos is given by: x=(50-3p)^2 where p is the price per dino, and x is the demand in weekly sales. a.) Find the Elasticity of Demand function E(p) and evaluate it at the price p = $5.Is the demand elastic, inelastic, or does it have unit elasticity? Explain what this means inyour own words. b.) Find the price Timmy needs to charge for his dinos in order to maximize revenue.(Round your answer to the nearest cent.)
a) define the income elasticity of demand? b) what is the normal and an inferior good?
If the income elasticity of demand for a good is -2.5, then it is a normal good, and its demand curve will shift to the left if buyers' incomes increase O it is a normal good, and its demand curve will shift to the right if buyers' incomes increase it is an inferior good, and its demand curve will shift to the right if buyers' incomes increase it is an inferior good, and its demand curve will shift to the left if buyers' incomes increase there is insufficient information to determine whether the good is normal or inferior

Take a picture of your workings and upload with your answer, or type out your workings. c) For the utility function above, what is the elasticity of demand of good x with respect to its own price? Take a picture of your workings and upload with your answer, or type out your workings.
Consider some determinants of the price elasticity of demand: • The availability of close substitutes • Whether the good is a necessity or a luxury • How broadly you define the market • The time horizon being considered A good with many close substitutes is likely to have relatively demand, since consumers can easily choose to purchase one of the close substitutes if the price of the good rises. A good's price elasticity of demand depends in part on how necessary it is relative to other goods. If the following goods are priced approximately the same, which one has the most elastic demand? O Sports car O Amputation procedures for diabetes sufferers The price elasticity of demand for a good also depends on how you define the good. Organize the goods found in the following table by indicating which is likely to have the most elastic demand, which is likely to have the least elastic demand, and which will have demand that falls in between.
PROBLEM (4) The demand for private jets (x) is given by QD= 20 - - P/² + Py where px is the price of jets, py is the price of yachts and I is the average income level. (a) Is a jet a normal or inferior good? Are yachts and jets substitutes or complements ?(explain your reasoning in a sentence) At the point I = px = py=10 calculate (b) the (own) price elasticity of demand (c) the cross price elasticity of demand (demand for jets with respect to the price of yachts) (d) the income elasticity of demand (Calculus help: the derivative of - is X X
Suppose a firm sells two goods, Good A and Good B. Use the following information to answer questions that follow:Profit maximising price of Good A = R200Profit maximising price of Good B = R75MC at Q* of Good A = R120Total revenue of Good A = R26000Total revenue of Good B = R24000Rothschild index of Good B = 0.4Price elasticity of the market demand for Good B = -2 2.1. Calculate each of the following:Ed of Good A = ____________Ed of Good B =__________MC at Q* of Good B = R___________ 2.2 Suppose that the firm noticed that when it increased the price of Good A from R200 to R300, the sales of Good B decreased from 1000 to 600 units. Calculate and classify the cross-price elasticity of demand between Good A and Good B.Ec =____________Good A and Good B are classified as (substitutes/compliments) 2.3. Use the elasticity coefficient calculated above and the information provided, to calculate by how much the firm’s total combined revenue will change if it decreases the price of Good A by…
Consider the demand for a luxury good such as a yacht. You can plot three different straight lines through the three points X, Y, and Z on this graph. Place the blue line (circle symbol) so that it goes through two of the points and shows the most likely demand curve for this type of good. Hint: Consider the relative elasticities of the different possible demand curves. 120 100 Demand Curve メ) 60 メャメマ 40 20 0. 2. 4. 6. 8 10 12 LUXURY GOODS (Thousands per year) 14 16 PRICE (Dollars per yacht)

Categories Most Elastic In Between Least Elastic Food Red bell peppers less Vegetables more The price elasticity of demand is also affected by the given time horizon. no more, nor less, Compared to the short-run demand for oil, the demand for oil in the long run will tend to be elastic.
What is the relationship between price elasticity and position on the demand curve? For example, as youmove up the demand curve to higher prices and lower quantities, what happens to the measured elasticity? How would you explain that? Income effects depend on the income elasticity of demand for each good that you buy. If one of the goods you buy has a negative income elasticity, that is, it is an inferior good, what must be true of the income elasticity of the other good you buy?
