5. 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 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?
