?Show Algebra Demand Changes: Scenario 1 Description of market events that would change commuter demand for gasoline... For Wayland, gasoline and road-trip vacations are complement goods. The price of a hotel room declines making the cost of road trips less expensive. By dragging the demand curve left or right or selecting the quantity demanded, show the effect that this event will have on Wayland's demand for gasoline. Demand Schedule Price $2.50 $3.00 $3.50 $4.00 $4.50 Quantity (D1) 97.5 78.5 66 58.5 54.5 Quantity (D2) 106.45 87.45 74.95 67.45 63.45 • Curve Shift Quantity Demanded Price ($ per gallon) 4.75 4.5 4.25 4 3.75 3.5 3.25 3 2.75 2.5 D1 D2 2.25 20 30 40 50 60 70 80 90 100 110 120 Quantity (Millions of Gallons)

Demand and supply often shift in the retail market for gasoline. Below are two demand curves and two supply curves for gallons of gasoline in the month of May in a small town in Maine. Some of the data are missing. Using the table, answer the following questions: Price | Quantities Demanded | Quantities Supplied | D1 | D2 | S1 | S2 $5.00 | 5,000 | 7,500 | 9,000 | 9,500 | 6,000 | 8,000 | 8,000 | 9,000 3.00 | | 8,500 | | 8,500 | | 9,000 | 5,000 | a. Use the following facts to fill in the missing data in the table. If demand is D1 and supply is S1, the equilibrium quantity is 7,000 gallons per month. When demand is D2 and supply is S1, the equilibrium price is $4.00 per gallon. When demand is D2 and supply is S1, there is an excess demand of 4,000 gallons per month at a price of $2.00 per gallon. If demand is D1 and supply is S2, the equilibrium quantity is 8,000 gallons per month.

The figure below illustrates three different demand curves for gasoline. In each case, the initial equilibrium price is $3.50 per gallon with 16 million gallons exchanged. As a result of a permanent increase in the price of gasoline to $5.00 per gallon, the quantity demanded may remain the same, fall to 4 million gallons, or fall to 13 million gallons depending on whether we consider the immediate run, the short run, or the long run. Use the midpoint method to calculate the price elasticity of demand in each period as the price increases from $3.50 to $5.00. Give all answers to two decimals. immediate run: short run: long run: Gasoline Price D1 7.5 7 6.5 6 5.5 4.5 4 3.5 3 2.5 2 1.5 1 0.5 0 D3 D2 Quantity (in millions of gallons)
Demand for Gasoline The following table shows the demand for gasoline in the United States in terms of the price per gallon: ${ }^{37}$ $$ \begin{array}{r|c|c|c|c} \begin{array}{r} \text { Price } p \\ \text { (\$/gallon) } \end{array} & 1.50 & 2.50 & 3 & 3.50 \\ \hline \begin{array}{r} \text { Demand } q \\ \text { Demanday) } \end{array} & 1.7 & 1.65 & 1.55 & 1.4 \\ \hline \text { gallons sold/person/day } & & & & \\ \hline \end{array} $$ Which of the following kinds of models would best fit the given data? Explain your choice of model. $(A, a, b,$ and $c$ are constants.) (A) $q=A b^{p} \quad(b>1)$ (B) $q=A b^{p} \quad(b<1)$ (C) $q=a p^{2}+b p+c \quad(a>0)$ (D) $q=a p^{2}+b p+c \quad(a<0)$
