s=g3
s equals Start Fraction g over 3 End Fraction

s=3g
s equals 3 g

s=3+g
s equals 3 plus g

g=3s

Answer 1

The correct equation that expresses the relationship between the number of gallons of gas \( g \) and the total amount of money \( s \) that Anja spends is:

\[ s = 3g \]

This equation means that the total amount \( s \) spent is equal to the cost per gallon ($3) multiplied by the number of gallons \( g \).
