Question

Tiana's math test score are 85 and 91 . She has one more test left. In order to earn and A, her average test score must be at least 94. Let x represent Tiana's score on her next test. Which inequalities could represent the possible test scores she can earn on the next test in order to earn an A? Select all that apply

A) 94<85+91/2<100
B) 94<176+x/2<100
C) 94<85+91+x/3<100
D) 94<176/3<100
E) 94<=176+x/3<100

Answer 1

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.

Answer 2

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.
