You can put this solution on YOUR website! The demand and supply equations for a certain item are given by
D = –5p + 40
S = –p^2 + 30p – 8
Find the equilibrium price
Equilibrium is when supply = demand;
Use quadratic equation to solve;
Now we two equations to solve, because we have 35+ and 35-;
P=33.57
P=1.43
