Question 1005188
Paul's second test score was 8 points higher than his first test score. His third score was 88. He had a B average (between 80 and 89, inclusive) for the three tests. What can you conclude about his first test score? It was between: 
-------
1st:: x
2nd:: x+8
3rd:: 88
-----
Sum = 2x + 96
----
Solve::
80 < 2x+96 < 89
---
-16 < 2x < -7
---
-8 < x < -3.5
