The weekly demand and supply functions for sportsman 5 × 7 tents are given by
p = −0.1x^2 − x + 33
p = 0.1x^2 + 2x + 13
respectively, where p is measured in dollars and x is measured in units of a hundred. find the equilibrium quantity. find the equilibrium price.

The equilibruim point of a demand and supply function is the point at which the quantity demanded is equal to the quantity supplied.

Given the demand function as

and the supply function as


The equilibruim quantity is obtained as follows:


There is no real equilibruim quantity and price for the given demand and supply function.
