Math Problem Statement
The Unique Gifts catalog lists a "super loud and vibrating alarm clock." Their records indicate the following information on the relation of monthly supply and demand quantities to the price of the clock.
Demand Supply Price
168
133
$31
138
173
$55
Use this information to find the following.
(a) points on the demand linear equation
(x, p) =
(smaller x-value)
(x, p) =
(larger x-value)
points on the supply linear equation
(x, p) =
(smaller x-value)
(x, p) =
(larger x-value)
(b) the demand equation p p =
(c) the supply equation p p =
(d) the equilibrium quantity and price
Equilibrium occurs when the price of the clock is $ and the quantity is
