Question

Safety standards require a pool to add 3 chlorine tablets to every 2,000 gallons of water. Today, the lifeguards at Park Pool added 8 chlorine tablets to their pool's 10,000 gallons of water.

How does Park Pool's chlorine compare to the safety standards?
Choose 1 answer:

A
Park Pool has more chlorine than the safety standards require.

B
Park Pool has less chlorine than the safety standards require.

C
Park Pool has the right amount of chlorine.

Answer 1

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 2

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.
