_____
The distributive property applies.
1.42·10⁷ tons + 1.07·10⁷ tons = (1.42 + 1.07)·10⁷ tons = 2.49·10⁷ tons
Answer:
Option A
Step-by-step explanation:
The amount of e waste generated in a region during two years was 14,200,000 tons and 10,700,000 tons.
So total e waste generated over these two years will be
= 14200000 + 10700000
= 24,900,000
Now we have to express the total amount in the scientific notation.
24900000 = 2.49 × 10000000
= 2.49 × 10⁷
Option A is the correct answer.
