Question 395510
Greg's first three test scores were consecutive even integers. 
You have to symbolize even integers as multiples of 2.
1st: 2x-2
2nd: 2x
3rd: 2x+2
---
His fourth score was 76. 
--------
If his test average on the four test scores was between 82 and 84, what was his lowest possible test score?
---
Inequality:
82 < [2x-2+2x+2x+2+76]/4 < 84
-----
82 < [6x+76]/4 < 84
----
328 < 6x+76 < 336
---
252 < 6x < 260
---
42 < x < 43 1/3
----
=============================
His test scores:
2x-2 = 2*43-2 = 84
2x = 86
2x+2 = 88
---
76 is the lowest of the 4 scores.
