Colin buys gas for her car at $4 a gallon. Write an equation using two variables to show the relationship between the number of gallons of gas, g, and the total amount she spends, s.

what is answer and it is not 4g

?

The correct equation is:

s = 4g

This equation shows that the total amount spent, s, is equal to the cost per gallon, $4, multiplied by the number of gallons purchased, g.

i keep getting it wrong it is not that answer keep getting it wrong it is not that answer

Apologies for the confusion. Let's try another equation:

Let the total amount spent be "s" and the number of gallons purchased be "g". If Colin buys gas for her car at $4 a gallon, then the equation to show the relationship between the number of gallons of gas and the total amount she spends is:

s = 4g

In this equation, "s" represents the total amount spent on gas, and "g" represents the number of gallons purchased. Each gallon costs $4, so the total amount spent is equal to the cost per gallon multiplied by the number of gallons purchased.
