- Given the following supply and demand functions find the equilibrium price and quantity in the market: Qd=195-20P Qs=-5+5Parrow_forwardAssume the demand curve for gasoline is downward sloping and the supply curve is upward sloping. Start by considering the gasoline market in 2020. Draw a graph that shows supply and demand analysis for gasoline in this city. Label the supply curve as S0; demand curve as D0; the equilibrium price as P0; and equilibrium quantity as Q0.arrow_forwardA small province is planning to levy a hotel room tax of $20 per night on hotel owners to recover some of the costs of government services associated with nonresidents. The average price of a standard hotel room in this province before the implementation of the tax is $150 per night. Market analysts predict that the average price of a hotel room will increase to $155 per night after the tax. a) Use the supply and demand model to illustrate and explain how the proposed tax on hotel operators will impact the market for hotels. Clearly show in your diagram and explain in words the impact on price and quantity of hotel rooms as well as the revenue raised and any deadweight loss caused by the tax. b) Discuss how tax incidence is shared between buyers and sellers. What share of this tax is paid for by buyers, and what share is paid for by sellers? c) What do your findings in part b tell you about the price elasticity of demand for hotel rooms compared to the price elasticity of supply?…arrow_forward
- QUESTION 3 Inthe demand equation is D(x) = 79 - 1.65x and the supply equation is S(x) =0.71x+21, find the equilibrium prce. QUESTION 4 If the demand equation for an item is D(x) = -2.2x + 510 and a supplier is willing to supply 90 items at $700 per item, or 120 items at $2100 per item, find the equilibrium quantity, assuming linear supply and demand models.arrow_forwardQ1. Suppose the demand curve for pizza in the café is given by Q=300 - 20P- 20P1, where P1 is the price of soda. The supply curve is Q=10P - 10. a) If the price of soda is P1= 5. Find the equilibrium price and quantity of pizza. b) Due to a price change of soda, the market equilibrium price per slice of pizza changes to P*=5. What must be the price of soda now? c)Calculate the cross-price (soda) elasticity of demand (pizza) at the equilibrium point in b), and determine whether pizza and soda are substitute or complement in this example?arrow_forwardLet the supply and demand functions for raspberry-flavored licorice be given by p = S(q) = q and p = D(q) = 90 - q ,where p is the price in dollars and q is the number of batches. Graph these functions on the same axes (graph the supply function as a dashed line and the demand function as a solid line). Also, find the equilibrium quantity and the equilibrium price.arrow_forward
- 8. Given the following set of demand and supply functions, find the equilibrium price and quantities. (i) Qd = 450 - 3P; Qs = 50+ 5P, (ii) Qd = 500 - 3P; Qs = 100; (iii) Qs = 30 + 1/2p, find Qs, when P =2. P = 4, P = 6, p = 10 9. A) Briefly discuss the microeconomics goals b) With the help appropriate diagram briefly discuss a change in QTY demanded & change in demand.arrow_forwardAssume that the demand curve D(p) given below is the market demand for widgets: Q = D(p) = 1183-12p, p > 0 Let the market supply of widgets be given by: Q = S(p) = -5 + 10p, p > 0 where p is the price and Q is the quantity. The functions D(p) and S(p) give the number of widgets demanded and supplied at a given price. What is the equilibrium price? Please round your answer to the nearest hundredth. What is the equilibrium quantity? Please round your answer to the nearest integer. What is the total revenue at equilibrium? Please round your answer to the nearest integerarrow_forwardQ3. Assume that the demand curve D(p) given below is the market demand for widgets:Q=D(p)=2372−19p, p > 0 Let the market supply of widgets be given by:Q=S(p)=−3+6p, p > 0 where p is the price and Q is the quantity. The functions D(p) and S(p) give the number of widgets demanded and supplied at a given price.What is the equilibrium price? Please round your answer to the nearest hundredth.What is the equilibrium quantity? Please round your answer to the nearest integer.What is the price elasticity of demand (include negative sign if negative)? Please round your answer to the nearest hundredth.What is the price elasticity of supply? Please round your answer to the nearest hundredtharrow_forward
- Gasoline for cars is produced in a market. There are equations for the Supply and Inverse Demand of car gasoline that model its Supply and Demand graph. These equations are (for supply), P = 20 + Qs, and (for Inverse Demand), P = 80 - Qd. Due to gasoline shortages, some sellers may be able to get access to more gasoline and produce it better than others. As a result, the federal government placed a quantity restriction of 15 units on the sellers. (Part I) Draw the market equilibrium with the government intervention (Q** and P**) of the quantity restriction. Please label the graph for slopes, the equilibrium point, etc. (Part II) What is the market equilibrium without the intervention of the government? (Part III) The government decided that the previous quantity restriction was not sufficient. So, it increased the restriction from 15 units to 20 units. Consequently, what is the new market equilibrium point with this new intervention? It is not necessary to label this point on the…arrow_forwardBy providing an example, explain three factors that might shift the demand curve for a product inward (to left).arrow_forwardNonearrow_forward
