hi
Does someone have an idea?
1, The concentration of a certain chemical in a full water tank depends on the depth of the water. At a depth that is x feet below the top of the tank, the concentration is parts per million, where 0 < x < 4. To the nearest 0.1 foot, at what depth is the concentration equal to 6 parts per million?
(A) 2.4 ft
(B) 2.5 ft
(C) 2.8 ft
(D) 3.0 ft
(E) 3.2 ft
concentration

Hi, Chrystelle
I think your transcription of the problem might be missing some info - possibly at the line that says "the concentration is parts per million" - is there supposed to be a value between "is" and "parts"? As written, there is not enough information given in the problem to solve it. Please do post again if you figure out what is missing.
