To determine the total amount in volume of gasoline used by Serena in a week, we need the data on the distance she drive per week and the any value relating to the amount of gasoline used. We calculate as follows:
25 miles / 15 miles per gallon + 35 miles / 23 miles per gallon = 3.19 gallon of gasoline used per week
