Anja buys gas for her car at 3 per gallon. Write an equation using two variables to show the relationship between the number of gallons of gas g and the total amount of amount she spends s

g=3s
s=3+g
s=g/3
s=g3

s = 3g

are you 100% sure

I apologize for the mistake in my earlier response. The correct equation should be:

s = 3g

This equation shows the relationship between the total amount spent on gas, s, and the number of gallons of gas purchased, g, at a rate of $3 per gallon. Thank you for bringing this to my attention.
