Depends on too many factors to say exactly but probably 0-7. Depends on:
1) The other inquires currently reporting
2) Your scoring bucket
3) Your current scores
The closer you are to the mean the less your score is effected. You are quite high so if your score is effected it may be affected more. The first inquiry in a 12 month perion usually has a very minor effect. You are high enough that you really don't need to worry about it.
