The base charge for parking for 4 hours at a rate of 2 per hour would be 8 (2 x 4). However, the charged amount is only 6. To find the percentage saved, subtract the charged amount from the base charge: 8 - 6 = 2. Then, divide the savings by the base charge and multiply by 100: (2/8) x 100 = 25%. Therefore, 25% is saved on the base charge for a vehicle parked for 4 hours.
