Question

1/Consider the demand curve Q=100-50P. Draw the demand curve and indicate which portion of the curve is elastic, which portion is inelastic, and which portion is unit elastic.

2/

Suppose the demand for crossing the Golden Gate Bridge is given by Q=10,000 – 1000P.

If the toll (P) is $3, how much revenue is collected? (15 points)

What is the price elasticity of demand at this point? (10 points)

Could the bridge authorities increase their revenues by changing their price? How? (15 points)

Answer #1

1) Q=100-50P.

P=2-(Q/50)

The point of intersection between the vertical axis and the demand curve is perfectly elastic.

The point of intersection between the horizontal axis and the demand curve is perfectly inelastic.

Exactly middle of the demand curve is unit elastic.

The segment between the price axis intercept and the middle point is relatively elastic. And the segment between the quantity axis and the middle point is relatively inelastic.

Suppose you are in charge of a toll bridge that costs
essentially nothing to operate. The demand for bridge crossings Q
is given by P = 15 − Q/2, where P is the price of the toll and Q is
the number of vehicles crossing the bridge.
(a) (2.5 points) Draw the demand curve for bridge crossings as a
function of the toll price.
(b) (2.5 points) How many people would cross the bridge if there
were no toll?
(c)...

Draw the demand curve of Apple and calculate the price
elasticity for their main product or service. Determine if they
have an elastic or inelastic demand curve.

how
do you draw the demand curve q=250-10p
calculate the price elasticity of demand at prices of $5, $10, and
$15 to show how it changes as you move along this linear demand
curve

Demand elasticity and social loss. Consider two
vaccines for different viruses ? and ?. Assume that the marginal
cost of producing both drugs is constant and that the fixed cost is
small. In other words, assume that the supply curve for both drugs
is flat (horizontal).

Suppose that demand for vaccine ? is price elastic, whereas
demand for vaccine ? is relatively inelastic. Using the graphs
above, draw two demand curves: one...
