i also need help with this one:
Supply and Demand let the supply and demand functions for butter pecan cream be given by.
P= s(q)= (2)/(5)q and p = D(q) = 81- (3)/(4)q
where p is the price in dollars and q is the number of batches.
A) Find the equilibrium quantity and the quilibrium price.
is there a formula for this because i am not understanding?
