You can put this solution on YOUR website! A car can be rented from Continental Rental for $80 per week plus 25 cents for each mile driven. How many miles can you travel if you can spend at most $400 for the week?
-------------
Let # of miles driven be "x".
INEQUALITY:
0.25x + 80 <= 400
0.25x <= 320
x <= 1280 miles (miles driven)

You can put this solution on YOUR website! If you pay $80 to rent the car, then you have $320 left to pay for the miles you are going to drive.
(That amount comes from $400 - $80 = $320).
.
At 25 cents per mile, you can drive 4 miles for each dollar you spend on mileage. (That comes
from miles per dollar)
.
And since you have 320 dollars to spend on mileage, at the rate of 4 miles per dollar you
can drive 320 * 4 = 1280 miles during the week.
.
Hope this helps you to see how you can think your way through problems such as this rather
than trying to develop and equation that you plug numbers into.
