The answer if 17.14%.

Now we have to write the equation x/57.14=30/100. We write this because we nee to find 30 percent of 57.14% from the total number of gallons. We can cross multiply, 57.14*30=17.1428571. Then we do 17.1428571/100 to get 0.171428571. We move the decimal two places to the right and we get 17.14%.
