A club currently has
300
members who pay
\$ 400
per month for membership dues. The​ club's board members want to increase monthly revenue by lowering the monthly dues in hopes of attracting new members. A market research study has shown that for each
\$ 1 decrease in the monthly membership​ price, an additional
3 people will join the club. What price should the club charge to maximize​ revenue? What is the maximum​ revenue?

1. Suppose there are x price decreases.
so, price is 400-x
membership is 300+3x
revenue is thus (400-x)(300+3x)
= -3x^2+900x+120000

So, just find the vertex of the parabola to determine price and max revenue.
