Price–demand equation. The marginal price for a weekly demand of x bottles of shampoo in a drugstore is given by p ′ ( x ) = − 6 , 000 ( 3 x + 50 ) 2 Find the price-demand equation if the weekly demand is 150 when the price of a bottle of shampoo is $8. What is the weekly demand when the price is $6.50?
