Final Jeopardy
Jen wants to average 92 on her 5 math tests.
After taking 4 tests, her average is 90. What
does she need to score on her 5th test so that
she averages 92 overall?
Click my picture to see the answer
54
Final Jeopardy Answer
To average 90 on 4 tests means the total number
of points accumulated is 90 x 4 or 360
points. To average 92 on 5 tests means the
total number of points accumulated is 92 x 5 or
460 points. Since 460-360 100, Jen must get
100 or 100 points on the 5th test to average 92.
