D. 24.9 × 10^14 tons

Answer 1

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

$Total=14200000+10700000$

$Total=24900000$

We need to convert it in scientific notation.

$Total=2.49\times 10000000$

$Total=2.49\times 10^7$

Therefore the correct option is A.
