Question 1201210
<br>
The response from the other tutor shows a formal mathematical solution... which possibly is what was wanted.<br>
If a formal algebraic solution is not required, you can solve a simple averaging problem like this one as follows:<br>
His point total on the first two quizzes is 14; to get the desired average of 8, his point total would have to be 16.  So on the first two quizzes he is 2 points BELOW where he needs to be.<br>
That means on the next quiz, in order to reach his desired average, his score needs to be 2 points ABOVE the desired average.<br>
ANSWER: The required score on the next quiz is 8+2 = 10.<br>
