Answer:

B. 2.785 x 10^5 mL

Explanation:

You want to first turn 2.7 x 10^5 mL to it's standard form.

2.7 x 10^5 mL means 2.7 x 10000 mL. This equals 270,000 mL

Now we can add the 8,500 mL to 270,000 mL = 278,500 mL

Now that we know that the dog's water bowl plus the horse's water through is 278,500 mL, we wil convert it to scientific notation

We will count decimal places backwards and it should result in 5 decimal places meaning we will use "10^5" in our notation. This also means the form of 278,500 we will be using is 2.785

So the answer is 2.785 x 10^5

Hope this helps!
