- As the price of GOOD A increases by 20%, the quantity demanded of GOOD B increases by 10%. What is the relationship of the two goods? Show the necessary computation to support your answer.3. Determinants of demand The following graph shows the demand curve for sedans (for example, Toyota Camrys or Honda Accords) in New York City. For simplicity, assume that all sedans are identical and sell for the same price. Initially, the graph shows market demand under the following circumstances: Average household income is $50,000 per year, the price of a subway ride is $2.00 per ride. Use the graph input tool to help you answer the following questions. You will not be graded on any changes you make to this graph. Note: Once you enter a value in a white field, the graph and any corresponding amounts in each grey field will change accordingly.

Consider a demand curve of the form QD=-2P+20, where QD is the quantity demanded of a good and P is the price of the good. Graph this demand curve. Also draw a graph of the supply curve Qs =2P-4, where Qs is the quantity supplied. Be sure to put P on the vertical axis and Q on the horizontal axis. Assume that all the Qs and Ps are nonnegative for parts a, b, and c. At what values of P and Q do these curves intersect-that is, where does QD = Qs ? b. Now, suppose at each price that individuals demand four more units of output-that the demand curve shifts to QD - 2P+24. Graph this new demand curve. At what values of P and Q does the new demand curve intersect the old supply curve-that is, where does QD = Qs ? c. Now finally, suppose the supply curve shifts to Q's=2P-8. Graph this new supply curve. At what values of P and Q does QD=Q's? Show all working calculations and label garph with…

Answer the following questions assuming the price of a pizzeria pizza is $10 and income is $10, unless otherwise noted. a) On a graph, Label the axes for the market for frozen pizzas. b) Plot a point at the horizontal intercept of the demand curve, given the assumptions at the start of the problem. c) Plot a point at the vertical intercept of the demand curve, given the assumptions at the start of the problem. Connect your points and label your curve.Mr. Hildago will experience a substantial increase in income when he accepts a new position at work. Even though the responsibilities of his new job are more taxing, he is excited to spend some of his higher income Mr. Hildago knows that a good can be characterized as either a normal good or an inferior good and that whether he buys more or less of the good depends on whether or not the good is normal or inferior The demand curve in the diagram to the right represents a normal good. Using the line drawing tool, illustrate the correct direction of the shift of the demand curve due to Mr. Hildago's increase in income. Properly label this line Carefully follow the instructions above and only draw the required object Quantity

Suppose the price of acoustic guitars decreases. (Assume that people regard electric guitars and acoustic guitars as substitutes.) Show the effect of this change on the market for electric guitars by shifting one or both of the curves on the following graph, holding all else constant. Note: Select and drag one or both of the curves to the desired position. Curves will snap into position, so if you try to move a curve and it snaps back to its original position, just drag it a little farther. PRICE (Dollars per guitar) Supply Demand Demand 1 Supply
