Question

Hucks bowling average over 5 games was 100 . He scored 118 on the next game . What was his new average.

Answer 1

103, 100x 5 games =500 over 5 games plus 118 is 618 over 6 games. Divide by 6 games is 103

Answer 2

Since his average over 5 games was 100, to get that average you'd have to do 5 100's divided by 5, so reversing that we now have 500 (to calculate average you add all the numbers then divide by how many numbers are present). So adding 500 and 118, adding all the numbers of his 6 total games, then you'd divide by 6 because you have six numbers present, so his new average would be 103 points.
