Answer:

A

Explanation:

Although rounding is needed, this answer makes the most sense.

If the question is (2.5 x 10^3) + (3.5 x 10^2):

= (2.5 x 1000) + (3.5 x 100)

=(2500) + (350)

= 2850.

Taking out the 10^3 with scientific notation leaves us with 2.85 x 10^3. Because this isn't an answer choice, A is the closest.
