A student has test scores of 90, 74, 82, and 90. The next test in the fianl examination, which will count as two test. What score does the student need on the final examination to produce an average score of 85
----------------------------
Let the final exam score be "x".
---------------
EQUATION:
(90+74+82+90+2x)/6 = 85
510 = 336+2x
2x = 174
x = 87
