The following table shows worldwide sales of a certain type of cell phone and their average selling prices in 2012 and 2013. Year 2012 2013 Selling Price ($) Sales (millions) 928 1,144 375 335 (a) Use the data to obtain a linear demand function for this type of cell phone. (Let p be the price, and let q be the demand). q(p): -5.4p + 3185 X Use your demand equation to predict sales if the price is lowered to $255. 1808 x million phones (b) Fill in the blank. For every $1 increase in price, sales of this type of cell phone decrease by 5.4 million units.

Don’t know what steps to take to be able to solve correctly

Suppose that the relationship between price, P, and quantity, Q, is given by the equation Q = 50 - 2P. Which of the following equations correctly represents solving Q = 50-2P for P? O P = 50+ Q OP=50-20 OP=25-2Q OP=50-Q ⒸP = 25- Q Plot the relationship between P and Qon the following graph. Note: Price (P) is on the vertical axis and quantity (Q) is on the horizontal axis. PRICE 40 35 30 25 15 10 5 0 5 10 15 The slope of this line is -0.50 QUANTITY 30 A 35 Suppose that the P in this equation refers to the price Julie is willing to pay for an additional magazine, and the Q refers to the number of magazines to which Julie subscribes. Read the following statement carefully: "The more magazines Julie subscribes to, the less she is willing to pay for an additional magazine." Which of the following best summarizes the pattern of causality suggested by this statement? O A change in P causes a change in Q. O A change in Q causes a change in P. O The relationship between P and Q is not a causal…

There is a debate about whether sterile hypodermic needles should be passed out free of charge in cities with high illegal drug use. Proponents argue that doing so will reduce the incidence of diseases, such as HIV/AIDS, that are often spread by needle sharing among drug users. Opponents believe that doing so will encourage more drug use by reducing the risks of this behavior. As an economist asked to assess the policy, you must know the following: (i) how responsive the spread of diseases like HIV/AIDS is to the price of sterile needles and (ii) how responsive drug use is to the price of sterile needles. Assuming that you know these two things, use the concepts of price elasticity of demand for sterile needles and the cross-price elasticity between drugs and sterile needles to answer the following questions. Which of the following would have to be true for this policy to be beneficial to cities? 0 The price elasticity of demand for sterile needles is relatively elastic. The…

When sold for $790.00, a certain desktop has an annual supply of 129.5 million computers and an annual demand of 155.5 million computers. When the price increases to $865.00, the annual supply increases to 147.5 million computers, and the demand drops to 134.5 million computers. NOTE: Round slope and vertical intercept to 4 decimal places and use those rounded values to the end. (a) Assuming that the supply and demand equations are linear, find the supply and demand equations. Supply Equation p = Demand Equation p = esc (Note: The equations should be in the form p = mq + b where p denotes the price (in dollars) and q denotes the quantity (in billions). The slope and y-intercept should be accurate to 4 decimal places). (b) Find the Equilibrium price and quantity. Equilibrium price p = Equilibrium quantity q = 9- F2 A (Note: The equilibrium price should be accurate to 2 decimal places and quantity should be rounded to the nearest whole number, and the equilibrium price should include a…

What is the current price of gasoline and how many gallons of gasoline do you currently buy per month? How many gallons would you buy next month and how would your behavior change if the price fell by $1.25 per gallon? Also, based on that information, what is your price elasticity of demand for gasoline? Be sure to show how you calculated your price elasticity of demand.     current price of gas = $2.53 gallons of gas per month = 72 gallons no change for next month On the average I fill my tank up 3 times a month each time I go I spend $60-$65

2.2. Use a diagram to illustrate what will happen to the equilibrium price and quantity of a product if the demand for the product increases. Also mention three factors that can cause an increase in demand. (10)

MICROECONOMICS  Questions 3  ( ALL OF IT IS ONE QUESTION!!!) For article 3 write the number of the graph that best describes what happened. Fill in only the appropriate boxes in the chart for article 3 and be sure and indicate if it is an increase or a decrease.  For the graph use an arrow to indicate an increase or a decrease.

The easing Covid-19 pandemic is expected to reduce demand for medical masks this year, joining a group of companies that have forecast a decline in business from Covid-19 prevention. Masks became a billion-dollar business for the St. Paul, Minn., manufacturer starting in 2020, when the virus’s rapid spread sent consumers and healthcare workers looking to secure facial coverings to try to avoid infection. Now, as the latest U.S. surge caused by the Omicron variant fades, 3M said they are seeing slowing mask sales. WHICH GRAPH BEST FITS THE ARTICLE.   Graph # Graph…
