Explanation

Set up and solve an equation that expresses the gallons-to-liters proportion. Letting x equal the gallon equivalent of 80 liters:

1/3.785=x/80

3.785x=80

x=80/3.785~21.14

Among the five alternatives, choice (1) provides the smallest tank size that will accommodate 21.14 gallons (80 liters).
