Answer:

Not teenagers = 1120

Step-by-step explanation:

Total number of audience members = 1600

30% of the audience were teenagers.

It means 70% of the audience were not teenagers. It can be given by :

x = 70% of 1600

$x=\dfrac{70}{100}\times 1600\\\\x=1120$

Hence, 1120 audiences were not teenagers.
