Answer:
70 students
Step-by-step explanation:
As, 30% Mike surveyed
And these 30% are 21 students
So 30% of X = 21
= 30/100 x X = 21
= 30X = 2100
So X = 2100/30
X = 70
So 70 students were surveyed
Because each ticket costs 1 and she spends 8 she would be buying 8 tickets
She has 8 friends so each one would get 1 ticket
The answer is 1
