James has to refuel his plane. It used to cost $200 to refill the tank. He got an extra tank to double fuel capacity. Fuel prices also went up by 20%. How much does he pay now for fuel? Let's be accurate as possible.

The cost to fill a tank went up 200 * .2 = $40. So it cost 200 + 40 = $240 to fill the tank. That means he now pays 240 * 2 = $480.
The answer: 480.
