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?
1st - 80M , 2nd - 88M , 3rd - 96.8M
To find out how many more cars were on the road in year 3 compared to year 2, we first need to calculate the number of cars in each of those years.
Given that the number of cars increases by 10% each year, we can calculate the number of cars in year 2 by multiplying the number of cars in year 1 by 1.1 (since a 10% increase is equivalent to multiplying by 1.1):
Number of cars in year 2 = Number of cars in year 1 * 1.1
Number of cars in year 2 = 80 million * 1.1
Number of cars in year 2 = 88 million
Similarly, to find the number of cars in year 3, we multiply the number of cars in year 2 by 1.1:
Number of cars in year 3 = Number of cars in year 2 * 1.1
Number of cars in year 3 = 88 million * 1.1
Number of cars in year 3 = 96.8 million
Now, let's calculate the difference in the number of cars between year 3 and year 2:
Difference = Number of cars in year 3 - Number of cars in year 2
Difference = 96.8 million - 88 million
Difference = 8.8 million
Therefore, there were 8.8 million more cars on the road in year 3 compared to year 2.
