Problema Solution

Suppose the price p of bolts is related to the quantity q that is demanded by:

p = 540 - 4q2

where q is measured in hundreds of bolts. Suppose the supply function for bolts is given by

p = 4q2,

where q is the number of bolts (in hundreds) that are supplied at price p. Find the equilibrium price

Answer provided by our tutors

The equilibrium price is the market price where the quantity of goods supplied is equal to the quantity of goods demanded in a market.


we find the demanded quantity using the equation:


p = 540 - 4q^2


q^2 = (540 - p)/4


we find the supplied quantity using the equation:


p = 4q^2


q^2 = p/4


the quantity of goods supplied is equal to the quantity of goods demanded:


(540 - p)/4 = p/4


by solving we find:


p = 270
