Answer 2

The correct option is A.

Explanation:

It is given that the amounts of e-waste generated in a region for 2 years were 14,200,000 tons and 10,700,000 tons.

We need to find the total E – waste generated in the region for these two years.

Total E – waste generated in the region for these two years is

`Total=14200000+10700000`

`Total=24900000`

We need to convert it in scientific notation.

`Total=2.49* 10000000`

`Total=2.49* 10^7`

Therefore the correct option is A.
