Jen wants to average 92% on her 5 math

her 5th test so that she averages 92%
overall?

Click my picture to see the answer
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%.
