Question 147683: I need help on this question, I do not understand how to work the problem.
Demand equation. Helen's Health Foods usually sells 400 cans of ProPac Muscle Punch per week when the price is $5 per can. After experimenting with prices for some time, Helen has determined that the weekly demand can be found by using the equation
d = 600 - 40p,
where d is the number of cans and p is the price of per can.
a) Will helen sell more or less Muscle Punch if she raises her price from $5?
b) What happens to her sales every time she raises her price by $1?
c) Graph the equation.
d) what is the maximum price that she can charge and still sell at least one can?

Comment: 600 tells you the number she would sell if the price was zero;
-40 is the slope and tells you that she loses 40 sales for each dollar
the price is raised.
-------------------------------
a) Will helen sell more or less Muscle Punch if she raises her price from $5?
less because the slope is negative.
-------------------------
b) What happens to her sales every time she raises her price by $1?
Demand goes down by 40 cans.
----------------------------
c) Graph the equation.
-------------------
d) what is the maximum price that she can charge and still sell at least one can?
600 -40p >=1
-40p >= -599
p <= 14.975
