Answer:
2 different scores
Step-by-step explanation:
The first thing we must do is define what the average is, which would be the value of half. This means that the average of 7 scores would be adding 2 more scores than the 5 we already have.
It does not matter if they are greater or less than those that already exist, they should only be equal to or less than 100 (also integers) and therefore the mean would be the 4th value of those 7 scores after organizing them from highest to lowest.
