- In the regional market for housing, demand for single detached homes depends on the price of the house, PH, consumer income, N, and the price of a related good, townhouses, PT. The demand equation is Qd = 0.1N+0.05PT-0.02PH. Initially, average consumer income is N = $40,000 and the average price of townhouses is $300,000. Making these substitutions, we get Qd = 19,000 -0.02PH. This is our current demand equation. Suppose income changes from $40,000 to $50,000.

- I intend to sell food coupons from my restaurant to two groups of customers, namely, general consumers and students, whose demand curves are given by Qg and Q, respectively, Qg=500 -5P Q₁ = 200 - 4P; where Q stands for quantity demanded and P is price. (a) Can you graph the two demand curves with P on the vertical axis and Q on the horizontal axis? If I price the coupons at $35, can you identify the quantity demanded by each group? (b) Also, find the price elasticity of demand for each group at the current price and quantity. (c) Am I maximizing my revenue by charging $35 for each coupon? Explain. (d) What price should I charge from each group if I want to maximize the revenue collected from coupon sales? (e) Normally, sellers try to maximize profits instead of revenue. In this case, explain if maximizing revenue is equivalent to maximizing profitsThe change in a commodity's price p(t) is proportional to the excess demand for the commodity. If the Qd = 8 - 2p and Qs = 2 + p k is the constant of proportionality. Given p(0) = 5 and p(2) = 3, solve the first-order differential equation. [Use 2 decimal places where necessary] P(t) = + ED tThe price of a widget decreases from $5000 to $4000, and in response to the price change the quantity demanded increases from 4000 to 8000 units. Therefore, demand for widgets in this price range: (Use the midpoint formula and write your answer in absolute terms, meaning as a positive number)
- Suppose the supply of a good is given by the equation Q = −6+2P and the demand for the good is given by the equation QD = 14 - 2P, where quantity (Q) is measured in millions of units and price (P) is measured in dollars per unit. The equilibrium quantity in this market is 4 million PRICE (Dollars per unit) the following graph, plot the demand curve using the blue line (circle symbol) and plot the supply curve using the orange line (square symbol). Then place the black point (plus symbol) at the equilibrium price and quantity.

EquilibriumPrice & Demand In economic theory, we let z represent the number of items (called demand) a supplier will produce if the price of the item is p. For a particular item, if the price is $10 per item, then the demand is 577 items. However, if the price is raised to $33 per item, then the demand decreases to 393 items. Using this information, find the demand equation as a function of the price p? r(p)The change in a commodity's price p(t) is proportional to the excess demand for the commodity. If the Qd = 8-2p and Qs = 2 + p k is the constant of proportionality. Given p(0) = 5 and p(2) = 3, solve the first-order differential equation. [Use 2 decimal places where necessary] P(t) =

This 68% increase of price per kilo was primarily caused by excess demand for chicken meat. This is the result of the decrease in consumption for pork meat due to the threat of African Swine Flu (ASF). However, even though consumer shifted preferences, the increase in the price of chicken was perceived to be too high for the budget of consumers. Therefore, sellers realized decrease in their daily aggregate sales from 1,000 kilos to 700 kilos. 1. Illustrate the change in the market equilibrium through a graph. 2. What presumably happened to the total revenues of the sellers during the price hike period? a.) Compute the price elasticity of demand b.) Derive the total revenue before the hike (TR1), and after the hike (TR2).In the following scenarios, you will be given a product and an event. Determine what will happen to the demand for the product based on the event, what happens to the demand curve, and give the non-price determinant that caused it to occur. (chose from the 7 determinants listed in the notes). The first one is answered for you as an example. EXAMPLE/ Product - Hamburgers Event - The price of steak increases Answer/ Demand increases - Curve shifts right - Price of substitutes 1. Pepsi - The price of Coke decreases dramatically. 2. Steak - Incomes fall due to the recession 3. Hair dye - Hair dye is successfully advertised in the media. 4. Computer software - The price of computers goes down.
