Maria studied the traffic trends in India. She found that the number of cars on the road increases by 10% each year. If there were 80 million cars in year 1 of her study, how many more cars were on the road in year 3 compared to year 2?

Year 2 has 10% more cars than year 1: 80 million × 1.10 = 88 million. Year 3 has 10% more than year 2: 88 million × 1.10 = 96.8 million. The difference is 96.8 − 88 = 8.8 million, so the answer is 8,800,000 cars.
