You are on a 650-mile trip by car. Your car used eight gallons of gas to travel the first 210 miles of the trip at the same rate. How much more gas will you need to make it the rest of the way?

8/210 = x/650

Cross multiply and solve for x.
21
8/210 = x/440
210x = 3520
x = 3520/210
x = 16.76 gallons
