Question 886495
Mr. D's average of 4 weekly quizzes was 84. What grade should he get on the 5th quiz so he can raise his average to 86?
========
Let the 5th score be "x":::
Equation:
Average of 5 = average of t
--------------------------------
(4*84+x)/5 = 86
4*84 + x = 430
x = 430-336
---
x = 94
-----------
Cheers,
