Example 4: Modeling Demand with a Linear Function
The demand for gasoline as a function of price is known to be linear, and
if the price for gasoline is p = $3.50 per gallon, the demand per
month is q = 40 gallons,
► if the price is raised to p= $4.00 per gallon, the demand goes down
to q = 35 gallons.
(a) Find an equation for the demand q as a function of p.
(assume it is linear)
(b) At what price would consumers refuse to buy gasoline?
