The correct answer is not on the list of choices.
It must be either the second choice or the third choice,
and you must have copied it wrong.
('x' gallons) times (cost of 1 gallon) = $52
Divide each side by ('x' gallons) :
Cost of 1 gallon = $52 / x .
Divide the marked down price by the original. So this is 828.75/975=.85. Subtract that from 1 since the .85 is how much of the original price the new price is to get .15. The price markdown is 15%
First you add 12 to the other side and once you have that divide both sides by -2 and since what we’re dividing by is negative the inequality switches so the answer is a > -2
The answer to your question would be B.
I hope this helped:D
