Question 81300: I needed to create a linear equation or inequality for my math class.
I created c=pg(52)
Where c=$4664.40 (cost of gas for the year)
p=$2.99 (price of gas per gallon)
g= 30 (number of gallons used)
(52) Weeks for the year
My teacher asked me to graph my equation by doing the following:
Vary either the price of gas or the number of gallons.
How do I graph this equation by doing what my instructor suggested? I am confused ;0/ PLEASE HELP!!!
Answer by stanbon(75887) (Show Source): You can put this solution on YOUR website!
You can't; you have two many variables.
-------------
Let's say you want to vary the price of gas but want to
purchase no more than 12 gallons of gas per week to help
conserve fuel.
Then Cost = 12p where p is the price per gallon for gas.
Then you have a graph that looks like:

On this you can read the cost of your gas as it changes
from $0 per gallon to $5 per gallon.
