The demand function for electric fans is as follows: • Qx = 100 – 0.5Px + 0.03I + 3Py where: • Qx = quantity demanded of electric fans • Px = average price of an electric fan • I = average income • Py = average price of an air conditioner Assume that the average price of an electric fan is $50, an air conditioner costs $400 and average income is $4,000. Determine or calculate the following: 1. The slope of the demand curve, 2. If air-conditioners are complimentary or substitutionary to electric fans with respect to the coefficient and, 3. If electric fans are a normal or inferior good with respect to the income coefficient.

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…

The inverse demand for good X is given by Px=25-0.005Qx+0.15Py+0.1I where Px is the price of X, Py is the price of Y, I is income, and Qx is the quantity demanded of good X. The inverse demand is just price as a function of quantity instead of quantity as a function of price. To get the demand function, just solve the equation for Qx. You should do this before answering the following. Goods X and Y are . . . .. . . .. . . .. . . . .. . . . X is a . . .. . . . .. . . good.
