There were 65 people waiting in two lines to buy a snowball ice drink they were joined in the line by 11 more people a total of 9 people got their drinks and left how many people were still

67 people were still left waiting in line.

Step-by-step explanation:

If there are 65 plus 11 more, there'd be 76 people in line.

76 - 9 = 67 people still left waiting in line.
