Q:
Sanjay has quiz scores of 96%, 89%, 92%, 77%, 100% and 87%. What score does he need to make on the final quiz to have an overall average of 91%?
Accepted Solution
A:
First (96+89+92+77+100+87+x)/7=91
Then 96+89+92+77+100+87+X = 637
Next 541 + X = 637
Then subtract 541 from both sides
Final answer is x=96
