You can put this solution on YOUR website! there are 10 students in math class. Nine of them had the following final exam scores: 68%,47%,81%,96%,91%,84%,61%,66%,76% what would the tenth student need to earnon the final exam so that the average final exam score for all 10 students is 75%
---------------------------
(68+47+81+96+91+84+61+66+76+x)/10 = 75
---------------------------
(670+x) = 750
x = 80
