A) Park Pool added more chlorine tablets than required by safety standards.
B) Park Pool added the exact amount of chlorine tablets as required by safety standards.
C) Park Pool added less chlorine tablets than required by safety standards.
D) Park Pool added the chlorine tablets in a ratio consistent with safety standards

Answer 1

Park Pool added less chlorine than required by safety standards, requiring 15 tablets but only 8 were used.

Step-by-step explanation:

The question is to determine how the amount of chlorine added to Park Pool compares to the safety standards. According to the standards, 3 chlorine tablets are to be added for every 2,000 gallons of water. To find out how many tablets are needed for 10,000 gallons, you can set up a proportion: 3 tablets / 2,000 gallons = x tablets / 10,000 gallons. Solving for x gives you (3 tablets * 10,000 gallons) / 2,000 gallons = 15 tablets.

Since the lifeguards added only 8 chlorine tablets for the 10,000-gallon pool, we can see that they added less chlorine than the safety standards require. Comparing this to the provided answer choices, Park Pool added less chlorine tablets than required by safety standards, which corresponds to answer choice C: Park Pool added less chlorine tablets than required by safety standards.
