Answer:
A. 4.2 times
Step-by-step explanation:
Chlorine level of the pool as adjusted by Paula = 6.3 parts per million
Ideal Chlorine level as suggested by the magazine = 1.5 parts per million.
Thus, the number of times the ideal level of Chlorine that the current level is = current level ÷ ideal level
= 
The current Chlorine level is 4.2 times the ideal Chlorine level.
Repeating; it's .252525252525252525252525
The answer is 20 because if you divide 15:20 by 5, you get 3:4. hope this helps!
