Final answer:

The equation to represent the total cost, y, for x number of gallons of gasoline priced at $3.39 per gallon is y = 3.39x.

Step-by-step explanation:

The question asks us to write an equation that represents the total cost, y, of purchasing x number of gallons of gasoline, given that the price per gallon is $3.39. The equation to represent this is a simple linear equation based on the formula: total cost = price per gallon × number of gallons.

To write the equation, we would set it up as follows:

y = 3.39x

Here, y represents the total cost in dollars, and x represents the number of gallons of gasoline purchased.

Answer:

3.39x=y

Step-by-step explanation:

This is because the 'y' part is supposed to be the answer for how much the gallons of gasoline would be.

The 'x' part of the equation represents how much gallons of gasoline you got and you can treat it as a normal number.

Pretend that x is 2 and so you are to find out how much 2 gallons of gasoline costs and to work this out you would do this: 3.39 x 2.

You just basically treat x as a normal number like so and it would look like:

3.39 x x=3.39x
