The water acidity in a pool is considered normal when the average pH reading of three daily measurements is between 7.2 and 7.8. If the first tow pH reading are 7.48 and 7.85, find the range of pH value for the third reading that will result in the acidity level being normal.

The water acidity in a pool is considered normal when the average pH reading of three daily measurements is between 8.2 and 8.5 If the first two pH readings are 8.48 and 8.35 , then find the range of pH value for the third reading that will result in the acidity level being normal.

he water acidity in a pool is considered normal when the average ph reading of three daily measurement is between 7.4 and 8.2. If the first two ph reading are 7.48 and 8.42. Find the range of ph value for the third reading that will result in the acidity level being normal

The water aciditiy in a pond is considered normal when the average pH reading of three daily measurement is between 7.1 and 7.8. If the first two pH readings are 7.25 and 7.8,find the range of pH of the water of the pond for the 3rd reading that will result in the acidity level being normal.
