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 = 100, Jen must get 100% or 100 points on the 5th test to average 92%.
