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.

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

Demand/sales will fall by 40 units.
