Suppose you have been hired by a research firm trying to understand the market for Widgets (a hypothetical product). Your analysis of the data indicates that the Demand curve for Widgets is estimated to be linear and given by equation Qd = 150 – 3P and the Supply curve for Widgets appears to be linear as well and is estimated as Qs = 2P – 20.
Graphically draw these two curves, labeling all relevant points (such as intercepts for each line) on the horizontal and vertical axes.
c) State the mathematical domain and the practical domain of this relation.
d) Logically explain the shape of the graph in the practical domain.
What is the significance of the C-intercept?
What is the significance of the vertical asymptote?
e) Suppose the health ministry has allocated a 30 million dollar budget for this vaccination program. Using
your simplified fraction from part b), algebraically determine the percentage of the Alberta population that
would be inoculated. Confirm your answer by finding this point on your DESMOS graph.
f) if epidemiologists determine that 80% is required for herd immunity for this virus, what must the health
ministry set aside in their budget for the vaccination program? Use a calculator to find a solution here.
(1) Consider a modern city in which office employment has been steadily shifting from the city center to suburban locations along beltways. Suppose that the city improves its mass-transit system, decreasing the monetary and time costs of radial travel. Assume that the improvement in the transit system does not affect the spatial distribution of residents. Will the improvement in the system speed up or slow down the movement of office firms to the suburbs?

- Attempts 9. Exercise 3.9 The Sydney Transportation Company operates an urban bus system in New South Wales, Australia. Economic analysis performed by the firm indicates that two major factors influence the demand for its services: fare levels and downtown parking rates. Table 1 presents information available from 2005 operations. Forecasts of future fares and hourly parking rates are presented in Table 2. Table 1 Average Daily Transit Riders Average Downtown Round-Trip Fare Parking Rate Year 2006 2007 Average / 1 (2005) 5,000 (Dollars) 1.00 1.25 (Dollars) 1.00 Table 2 Round-Trip Fare Average Parking Rates (Dollars) 2.50 2.50 (Dollars) 1.50 Sydney's economists supplied the following information so that the firm can estimate ridership. Based on past experience, the coefficient of cross elasticity between bus ridership and downtown parking rates is estimated at 0.2, given a fare of $1.00 per round trip. This is not expected to change for a fare increase to $1.25. The price elasticity of…arrow_forwardConsider the specific-factors model with 2 goods: manufacturing and agriculture.

The government is considering to impose an import tariff on agricultural products. Which of the following is true? (a) The relative price of agricultural products will go down. (b) Capitalists will support this initiative. (c) Agricultural production will increase. (d) Marginal product of labour will decrease in manufacturing. Explain your answer clearly.arrow_forwardConsider the specific-factors model with 2 goods: manufacturing and agriculture.

- Hello! Can you please answer the remaining questions? [9] Suppose an environmental regulator is concerned with efficient emissions control. The regulator uses its perception about the aggregate marginal abatement cost to determine the emissions tax. What tax rate does the regulator set? [10] Suppose there is uncertainty about firms’ marginal abatement costs. Describe the relationship between AMAC and MD in which taxes would lead to lower efficiency losses compared to permits.arrow_forwardA key skill in economics is the ability to use the theory of supply and demand to analyze specific markets. With this assignment, you get a chance to demonstrate your ability to apply what you have learned to the coffee market. Be sure to answer all parts of each of the scenarios below. Students may utilize Paint, Word (the shapes tool), or hand draw the graphs. Scenario 2: Suppose the National Institute of Health publishes a study finding that coffee drinking reduces the probability of getting colon cancer. How do you imagine this will affect the market for coffee? Which determinant of demand or supply is being affected? Show graphically with before and after curves on the same axes. How will this change affect the equilibrium price and quantity of coffee? Explain your reasoning.arrow_forward2 Your current prices are $311 in the southwestern region, $278 in the western region, and $240 in the New England region. Your marginal cost is now $212.21. Given the predicted changes in the quantity demanded by region per problem 1 and using the stay even analysis %ΔQd = %ΔP/[%ΔP + ((P-MC)/P)], can you raise the price by 7% in any of the regional markets? State you conclusion and then show all the steps supporting your conclusion. Round to one decimal place, i.e. 10.135 is 10.1 (Note you are not being asked to compute the new price.).arrow_forward
- Based on the graphical representation in Figure 1, calculate the price elasticity of demand for ibuprofen. Address the following questions when crafting your answer: What impact would a price increase have on the demand for ibuprofen and on consumer surplus given the price elasticity of demand depicted in Figure 1? What factors usually influence a resource’s price elasticity of demand? In the real world, you might expect the consumption choices of ibuprofen to be affected by brand-name versions of ibuprofen, such as Advil. Would you expect the brand-named products to have the same elasticity of demand as generic ibuprofen?arrow_forwardThe following scenario examines the relationship between marginal and average values. Suppose Jelani is a high school basketball player. The following table presents their game-by-game results for foul shots. Fill in the columns with Jelani's foul-shooting percentage for each game and their overall foul-shooting average after each game.

Note: Plot your points in the order in which you would like them connected. Line segments will connect the points automatically. 100 90 80 70 60 50 40 30 20 10 0 8/10 6/10 1/5 3/5 8/10 0 2 GAME 3 80 4 5 Game Foul-Shooting Percentage Average Foul-Shooting…arrow_forwardAssume the Supply of Kidneys is expressed as: Qs = 800 +.2P Assume the Demand for Kidneys is expressed as: Qd = 16,000 - .2P Due to the 1984 act prohibiting the purchase and sale of organs for transplant, supply will be limited to the number of kidneys individuals will donate (the number of kidneys donated when the price = 0) Graphically, show the supply and demand for kidneys before prohibition.

- (a) Dividing MUX and MUY by their respective prices compute the weighted marginal utility or marginal utility of money expenditure and draw up Table 2 showing diminishing returns for the consumption of the 6 units? (b) Briefly state what you can infer on this equation; MUX/PX = MUY/PY as far as equi marginal principle and managerial economics is concerned? C)Given that MUX/PX and MUY/PY are equal to 6 when 5 units of X and 3 units of Y are purchased. By purchasing these combinations of X and Y, calculate the amount the consumer will spend and derive the maximum satisfaction from combination of these units. (d) Applying the above principle illustrate in terms of a figure, and draw marginal utility curves for goods X and Y. You need to use marginal utility and price i.e. Marginal utility per Kwacha spent on good X = MUX/PX, and that of Y = MUY/PY. The MUX/PX curve should be shown in figure (a) while the MUY/PY curve should be shown in Fig (b).

In particular, if the price is $26 per item, then the supplier wants to make only 555 items. However, if the price is $40 per item, then the supplier would want to make 485 items. Convert the information in this problem to two ordered pairs. What is the ordered pair associated with the lower price? What is the ordered pair associated with the higher price? Using these ordered pairs, what is the supply equation? Give your answer in slope-intercept form: y= Box 1 & 2: Enter answers as ordered pairs (don't forget the parentheses). Box 3: Enter your answer as an expression. Example: 3x^2+1, x/5, (a+b)/c Be sure your variables match those in the question.
