Answer:

The correct option is A.

Step-by-step 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

[tex]Total=14200000+10700000[/tex]

[tex]Total=24900000[/tex]

We need to convert it in scientific notation.

[tex]Total=2.49\times 10000000[/tex]

[tex]Total=2.49\times 10^7[/tex]

Therefore the correct option is A.
