[Related to Solved Problem #1] You own a hot dog stand that you set up outside
the student union every day at lunch time. Currently, you are selling hot dogs for a
price of $3, and you sell 30 hot dogs a day (point A on the diagram to the right).
You are considering cutting the price to $2. The graph to the right shows two
possible increases in the quantity sold as a result of your price cut. Use the
information in the graph (new quantities are given on the horizontal axis) to
calculate the price elasticity between these two prices on each of the demand
curves. Use the midpoint formula to calculate the price elasticities.
On the demand curve containing the points "A" and "B", the price elasticity of
demand for a price cut from $3 to $2 is. (Hint: Include the negative sign and
enter your response rounded to two decimal places.)
On the demand curve containing the points "A" and "C", the price elasticity of
demand for a price cut from $3 to $2 is. (Hint: Include the negative sign and…
The following graph shows the supply curve for sedans in an imaginary market. For simplicity, assume that all sedans are identical and sell for the same price. Two factors that affect the supply of sedans are the level of technical knowledge—in this case, the speed with which manufacturing robots can fasten bolts, or robot speed—and the wage rate that auto manufacturers must pay their employees. Initially, the graph shows the supply curve when robots can fasten 2,500 bolts per hour and autoworkers earn $25 per hour.
Suppose that the price of a sedan increases from $21,000 to $26,000. This would cause the quantity supplied of sedans to ________ (options: increase, decrease) , which is reflected on the graph by a ________ (options: shift of, movement along) the supply curve.
Suppose the workers' union negotiates a pay raise. This causes a _________ (options: leftward movement along, rightward movement along, leftward shift of, rightward shift of) the supply curve because the pay raise…
The following graph shows the market for pizzas in San Diego, where there are over a thousand pizza restaurants at any given moment. Suppose the
number of pizza restaurants increases significantly.
Show the effect of this change on the market for pizzas by shifting one or both of the curves on the following graph, holding all else constant.
Note: Select and drag one or both of the curves to the desired position. Curves will snap into position, so if you try to move a curve and it snaps back
to its original position, just drag it a little farther.

- A student was asked to draw a demand and supply graph to illustrate the effect on the market for premium bottled water of a fall in the price of electrolytes used in some brands of premium bottled water, holding everything else constant. She drew the graph to the right and explained it as follows: "Electrolytes are an input to some brands of premium bottled water, so a fall in the price of electrolytes will cause the supply curve for premium bottled water to shift to the right (from S, to S₂). Because this shift in the supply curve results in a lower price (P₂), consumers will want to buy more premium bottled water and the demand curve will shift to the right (from D, to D₂) We know that more premium bottled water will be sold, but we can't be sure whether the price of premium bottled water will rise or fall. That depends on whether the supply curve or the demand curve has shifted farther to the right.
