Given: 

Tiana's Math Scores: 85 and 91
Target Average Test Score: (at least 94) meaning this translates to "≥94"

Looking at the choices, only letter E) provides the right answer since it solely has a ≥94 expression. So we choose this choice.

The answer is E. This inequality best suits the given because in order to achieve an A she must have an average of the three test scores in which the last test score must be higher than or equal to 94.
