Question

Sue's average for nine games of bowling is 108. What is the lowest score she can receive for the tenth game to have a mean of 110?

Answer 1

128

Explanation:

Sue's average for 9 games of bowling is 108. Therefore, the total scores for the 9 games is:

`= 108 * 9`

`= 972`

To have an average of 110 in 10 games, her total score will be:

`= 110 * 10`

`= 1100`

Therefore, the lowest score that she can get will be the difference between the values calculated above and this will be:

`= 1100 - 972`

`\bold{= 128}`
