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 .(1 point)
A 8 = 3 + g
B 8 = 3g
C 8 = g/3
D g = 3s
The correct equation is:
s = 3g
This equation shows that the total amount spent, s, is equal to the price per gallon, $3, multiplied by the number of gallons purchased, g.
