Usually if it's an basic good, or very important one.
because the price fluctuations do not affect the quantity sold.
a good example of that would be milk, if the milk gallon is say $8, and a family needs 1 gallon daily, they buy it for $8.
if the price drops to $7, they might buy 2, but they only need 1 everyday, just in case they may get another.
if the price drops to $4 or even $3, they're not going to get 10 gallons, there's no need for it on an everyday basis, besides is a perishable.
now if the price goes up to $12, they still need it, and will buy it for $12.
Step-by-step explanation:
Consider the provided equation.
P=2(l+w)P=2(l+w)
We need to solve the equation for I.
Divide both the sides by 2.
{P}{2}=\frac{2(l+w)}{2}2P=22(l+w)
{P}{2}=l+w2P=l+w
Now isolate the variable I.
Subtract w from both side.
\{P}{2}-w=l+w-w2P−w=l+w−w
I{P}{2}-wI=2P−w
The value of the equation for I is I=\frac{P}{2}-wI=2P−w .
Idk but this might help o_o
Answer:
is the equation of perpendicular line.
Step-by-step explanation:
We are given , the equation of a line is 
We can deduce that the slope of the given line is 
The slope of its perpendicular line would be , 
Now using the point slope form, 
Use the given point 
substituing these.
Therefore the required equation of a line that is perpendicular to y=-0.3x. +6 and that passes through the point (3,-8) is y=\frac{x}{0.3} -18[/tex]
