Question

Maria studied the traffic trends in India. She found that the number of cars on the roads 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? 8,000,000 8,800,000 88,000,000 96,800,000

Answer 1

You would do

(1.1)(80,000,000)=88,000,000

That is the total cars for year two. To find the increase you would do

(1.1)(88,000,000)=96,800,000

Then you would subtract year 2 from year three

96,800,000-88,000,00=8,800,000

That gives you ur answer.

Answer 2

B) 8, 800, 000

Explanation:

The number of cars in year 1= 80,000,000

She found that the number of cars on the roads increases by 10% each year.

Now let's find 10% of 80,000,000

=
`(10)/(100) *80,000,000 = 8,000,000`

So the number of cars in year 2= 80,000,000 + 8,000,000

= 88,000,000

Now let's find 10% of 88,000,000.

=
`(10)/(100) *88,000,000 = 8,800,000`

So the number of cars in year 3= 88,000,000 million+8,800,000= 96,800,000

Now we have to find difference in year 3 compared to in year 2.

The difference in the cars in year 3 compared to year 2= 96,800,000 - 88,000,000

= 8,800,000

Therefore, the answer is B) 8, 800, 000
