Ilsia is driving home from work. She needs to buy gas and notices an Exxon-Mobil station on one side of the street and a Shell station on the other side of the street. Although run by different companies, the two stations sell gasoline at the same price.
a. The most likely reason that the price is the same is that
drivers need gas and are willing to pay whatever price a gas station charges.
consumers view gasoline from different gas stations as perfect substitutes.
government regulation requires both gas stations to charge the same price.
gas stations always make a profit, so they can charge any price they want.
b. If one station increases its price,
it will make a higher profit.
it will lose customers to the cheaper station across the street.
it will be fined by the government.
it will sell more gasoline.

- #9arrow_forwardSuppose a small town has two bakeries: Bakery A and Bakery B. The residents of the town have different preferences when it comes to buying bread. Bakery A produces high-quality bread and charges a price of $5 per loaf, while Bakery B produces standard-quality bread and charges a price of $3 per loaf. The demand for bread in the town can be represented by the following equations: Q_A = 200 - 10P_A + 4P_B Q_B = 150 - 6P_B + 2P_A Where: Q_A and Q_B are the quantities of bread demanded from Bakery A and Bakery B respectively. P_A is the price charged by Bakery A. P_B is the price charged by Bakery B. a) Calculate the quantities of bread demanded from Bakery A and Bakery B when P_A = $5 and P_B = $3. b) Calculate the quantities of bread demanded from Bakery A and Bakery B when P_A = $6 and P_B = $2. c) If Bakery A and Bakery B collaborate and decide to charge the same price, what price should they charge to maximize their combined revenue?

- When does inefficiency exist in an economy? when a good is distributed fairly among buyers when a good is not distributed fairly among buyers when a good is not being produced by the lowest-cost producers when a good is being consumed by buyers who value it most highlyarrow_forwardRefer to Figure 4-4. The figure above represents the market for iced tea. Assume that this is a competitive market. At an output of 30,000 units the marginal cost of iced tea is greater than the marginal benefit; therefore, output is inefficiently high. producers should raise the price to $3 in order to sell the quantity demanded of 30,000. the marginal benefit of iced tea is greater than the marginal cost; therefore, output is inefficiently low. the marginal benefit of iced tea is greater than the marginal cost; therefore, output is inefficiently high. bar Price $3 2 S D 0 10.000 20.000 30,000 Quantityarrow_forward1. In Town A there is only one newspaper, Daily Outrage. The demand for the paper depends on the price and the amount of scandal reported. The demand function is Q = 15SZP-3 where Q is the number of issues sold per day, S is the number of column inches of scandal reported in the paper, and P is the price. Scandals are not a scarce commodity in town A, but it takes resources to write, edit, and print stories of scandal. The cost of reporting S units of scandal is £10S and is independent of the number of papers sold. In addition, the cost to print and deliver the paper is £0.10 per copy and is independent of the amount of scandal reported in the paper. (a) Calculate the price elasticity of demand. Explain whether the price elasticity depends on the amount of scandal reported and whether the price elasticity is constant over all prices. Comment on the price sensitivity of the readers of the Daily Outrage. (b) Calculate the profit maximising price using the formula that writes marginal…arrow_forward
