Adam tried to compute the average of his 7 test scores. He mistakenly divided the correct sum of all of his test scores by 6, which yielded 84. What is Adam's correct average test score?

Adam mistakenly divided his test scores 6 times instead of 7. So if the average yielded 84 when divided by a 6, then you multiply by 6 84×6=504 So you divide 504 by 7 (the correct amount of test scores) 504÷7=72 which is often equivalent to a B- 72 is Adam's grade point average.

Number Of Tests=7
6*84=6(80+4)=480+24=504

504/7=72

Adam's correct average test score is 72.

Adam's correct average test score is 72. He mistakenly calculated the average based on 6 scores instead of 7. By correctly summing all scores and dividing by the correct number, we find 72 is his proper average.
