Hey there!

The correct answer is B

If they are supposed to add 3 for every 2000, that means they should have 6 for every 4000, and 9 for every 6000, and 12 for every 8000. This means they have less.

Hope it helps and have a great day!

Answer:

B

Explanation:

The requirement is 3 chlorine tablets per every 2,000 galloons of water.

The lifeguards added 8 chlorine tablets for 10,000 galloons of water.

To get from 3 tablets to 8 tablets, we multiply by 8/3.

By multiplying 2,000 galloons of water by 8/3, we acquire approximately 5,333 galloons of water.

Since 5,333 is less than 10,000, the Park Pool has less chlorine than the safety standards require.
