Fred paid $52 for x gallons of gas. If each gallon of gas costs the same, what is the expression for the cost of one gallon of gas?

52-x

52x

52x

52+x

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.

52x 52 multiplied by the number of gallons bought
