We know that she spent $46.20 for 12 gallons because she filled up her gas tank and the limit that her tank has is 12 gallons. In order to find out how much each gallon cost we can follow this route:
Lets try to create a simple ratio and then we can cross multiply:
If 12 gallons is $46.20
Then 1 gallon is $X.
Lets cross multiply, so 12 times x equal to 1 times 46.20.
12x=46.20
x=$3.85
