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

Then 96+89+92+77+100+87+X = 637

Next 541 + X = 637

Then subtract 541 from both sides

Final answer is x=96
