Problem 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?

Answer:

In the park's pool there are 7 less chlorine tablets as compared to safety standards.

Step-by-step explanation:

Number of chlorine tablets in 2,000 gallons water = 3 tablets

Number of tablets in 1 gallon of water = [tex]\frac{3}{2,000} tablets[/tex]

Number of tablet to be added in 10,000 gallons of water :

[tex]\frac{3}{2,000}\times 10,000 tablets=15 tablets[/tex]

Number of chlorine tablets added by lifeguard in 10,000 gallon water=8 tablets

Tablets of chlorine to be more added =

=15 tablets - 8 tablets = 7 tablets

In the park's pool there are 7 less chlorine tablets as compared to safety standards.
