Missing Dollar-yeezygod21

The paradox looks simple but how it was worded it looked tricky. The missing dollar was not missing after all because each lady paid $9 which will bring the total to $27 instead of $10 . The bill was $25 dollars however the waiter kept the 2 dollars as a tip, . And he gave back the three $1 bills to the three ladies. 25+2+3= $30.
