**Problem:**

Number Concepts-Integers (**InterMath)**
**In a class of 22 students, eight receive an 84,
10 receive a 92, and 2 receive a 96 on the last test. If the class
average was 90, what are possible scores for the other two students?**

**Solution:**
t= test scores
22 * t = 90 (22)
22 * t = 1980
(8*84) + (10*92) + (2*96) + x + y = 1980
1784 + x + y = 1980
x + y = 196
Therefore, the average of the other two students' test
scores must equal 98.
Avg (x + y) = 98
**The possibilities for the two students' test scores
are:**

100 and 96

99 and 97

98 and 98
