Suppose that the demand and supply curves for good X are: QD = 75 − 1.25P and QS = −60 + 2.50P A: Algebraically solve for the market equilibrium price and quantity, neatly showing your work. B: Neatly construct a graph and plot the demand curve, carefully showing the horizontal and vertical intercepts. On the same graph, neatly plot the supply curve, showing an intercept. Label the equilibrium.

Draw a demand and supply graph for each of the following questions. For each question, start by drawing a correctly labeled graph of the market for cookies in equilibrium. Your starting graphs should each have correctly labeled axes and demand and supply curves. Label the equilibrium price and quantity as p1 and p2 on the axes of each of the starting graphs. Show the effect on the equilibrium price and quantity in the market for cookies if the price of flour decreases. Determine which curve is affected by the change in the price of flour and whether it increases or decreases. On your graph, draw a new curve indicating the shift—either to the right or the left. Label the new equilibrium price and quantity as p2 and q2.
choose one in the brackets to fill in for the following question: If the wage rate for workers in car manufacturing rises, the (supply curve , quantity supplied ) for cars will [ increase, decrease, remain unchanged ) and the [ demand curve, quantity demanded) for cars will [ increase, remain unchanged, decrease) Consider a competitive market in equilibrium at (Q1,P1). When there is an increase in demand in this market, what exactly happens in this market? Help describe what happens by selecting the correct sequence of events from the drop-down menus below. [Advice: draw this situation in a competitive market diagram.] step 1:( creates an access demand at the original market price, this allows the market to clear at the original market price , this creates an excess supply at the original market price ) step 2: (this puts upward pressure on the price, this puts downward pressure on the price , this does not affect the price in this market ) step 3: ( there is an increase in supply, as…
Suppose the National Institutes of Health publishes a study finding that coffee drinking increases the probability of getting colon cancer. How do you imagine this will affect the market for coffee? Why? Which determinant of demand or supply is being affected? Show graphically with before- and after-curves on the same axes. How will this change the equilibrium price and quantity of coffee? Explain your reasoning.

Some have argued that higher cigarette prices do not deter smoking. While there are many arguments both for and against this view, some find the following argument to be the most persuasive of all: “The laws of supply and demand indicate that higher prices are ineffective in reducing smoking. In particular, higher cigarette prices will reduce the demand for cigarettes. This reduction in demand will push the equilibrium price back down to its original level. Since the equilibrium price will remain unchanged, smokers will consume the same number of cigarettes.”Do you agree or disagree with this view? Disagree - the reduction in demand will push the equilibrium price below its original level. Disagree - this confuses a change in demand with a change in quantity demanded. Agree - the price increase will ultimately leave cigarette consumption unchanged. Disagree - higher cigarette prices will actually increase the demand for cigarettes.

Answer the given question with a proper explanation and step-by-step solution. Which of the following statements is/are correct? i. An increase in the price of kettles will result in an increase in the supply of kettles. ii. An increase in the price of any of the factors of production will result in a leftward shift of the supply curve. iii. An increase in the wages of workers at Mr Juicy drink factory in Durban will result in a movement along the supply curve of Mr Juicy drinks, ceteris paribus. iv. In their supply decisions, producers take account of the prices of all the alternative products they can produce. a) Only i, ii , iii and iv. b) Only ii and iv. c) Only ii and iii. d) Only i, ii and iv.
The demand for rice is given by Q d=20-p and the supply is Q s=3p-20. a. Draw the demand and supply functions. Find the equilibrium quantity and price, and show them on the graph. b. Suppose due to drought the supply changes to 3p-30. The supply remains the same. Draw the new supply function on the same graph, and find the new equilibrium price and quantity. Has the demand increased or decreased? How did the equilibrium price and quantity change compared to part a.?
Suppose the market demand for shirts is given by Qd = 300 – 20P and the market supply for shirts is given by Qs = 20P – 100, where P = price (per shirt). i. Graph the supply and demand schedules for shirts between price = $5 through to $15 (increase in units of 1, i.e. 5, 6, 7…). ii. Using the equations provided, in equilibrium, how many shirts would be sold and at what price? iii. What would happen if suppliers set the price of shirts at $15? Explain the market adjustment process.
