Question 343436: I've already tried this, but not sure about the making inequalities stuffs. Here is the Question:
"Students tested the acidity of the campus pond over a three-day period. On Monda and Tuesday, the pH values were 6.75 and 7.86. Find the range of pH values for Wednesday'd reading that will result in a mean pH greater than 7.1 and less than 7.6."

7.1 < [(6.75 + 7.86 + x) / 3] < 7.6

21.3 < (14.61 + x) < 22.8

6.69 < x < 8.17
