Asked by Tricia
A student scores 83 and 91 on her first 2 tests. Write and solve a compound inequality to find the possible values for a 3rd test score that would giver her an average between 85 and 90 inclusive.
I know she has to score between 81 & 96 but I'm not sure how to show it the proper form.

3*85 <= 83+91+x <= 3*90
255 <= 174+x <= 270
81 <= x <= 96
255 <= 174+x <= 270
81 <= x <= 96

Your answer is wrong Steve because the average you have shown is not on the test AND it has to be between 85 and 90 therefore you are incorrect because you showed that it was 81 less than 96 which would be incorrect the correct answer is: 83 less than or equal to 83+91+n/3 less than or equal to 90;73less than or equal to N less than or equal to 94.

O 85- 83+91+ 3 <90, 81≤n≤96
O 5 <= 83 + 91 <= pi, - 2 <= n <= 3
90 <= (83 + 91 + n)/3 <= 85, 96 <= n <= 1
83 <= (83 + 91 + H)/3 <= 90, 73 <= H <= 94
