Naoki averaged 68% on 9 tests. If lowest score is omitted...

I will be applying for the Gauss Competition, so I'm studying EXTRA hard, and I may be posting here often! Here is my first question:

Naoki wrote (that is, took) nine tests, each scored out of 100 points. His average on these nine tests was 68%. If his lowest mark is omitted, what is his highest possible resulting average?

Thank you!

I would think, the highest possible average after the omission would be if he got a 0 on the lowest scored test.

x/9=0.68, x=6.12

6.12/8=0.765

A 76.5 is the highest possible after omitting the lowest score.
