    Story promlem solvers please help

    Demand Equation : Helen's Health foods usuallt sells 400 cans of Pro pac Muscle Punch per week when the price is $5 per can. After experimenting with prices for sme time, Helen has determined that the weekly demand can be found by using the equation

    d+600-40p

    Where d is thenumber of cans and p is the price per can.

    Will Helen sell more or less Muscle Punch if she reaises her price from $5?

    What happesn to her sales everytime she raises her price $1?


    Need help with this not good with story problems, Please

    No the coeficient of price in the demand function is negative so demand
    falls with increasing price.

    Demand/sales will fall by 40 units.
