Question 1028453: Suppose that the quantity supplied S and the quantity demanded D of baseball caps at a major league game are given by the function S(p) = 3400-90p and D(p)=110p, where p is the price. a) Find the equilibrium price for the caps at the game. B) Find the equilibrium quantity. I have no clue where to even start with this question.

+S%28p%29+=+3400+-+90p+
+D%28p%29+=+110p+
---------------------
I'm pretty sure that the equilibrium price
is where supply = demand, or
+S%28p%29+=+D%28p%29+
+3400+-+90p+=+110p+
+200p+=+3400+
+p+=+17+
(a) The equilibrium price is $17.00
---------------------
+S%28p%29+=+3400+-+90p+
+S%28p%29+=+3400+-+90%2A17+
+S%28p%29+=+3400+-+1530+
+S%28p%29+=+1870+
and
+D%28p%29+=+110p+
+D%28p%29+=+110%2A17+
+D%28p%29+=+1870+
------------------
(b) The equilibrium quantity is 1870
