The weekly demand for shampoo in a chain of drugstores is 1,160 bottles at a price of $3.79 each. If the price is lowered to $3.59, the weekly demand increases to 1,320 bottles. Assuming the relationship between the weekly demand and price per bottle is linear, find the demand equation. How many bottles would the stores sell each week if the price were lowered to $3.29?
