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](https://tex.z-dn.net/?f=x%3D%5Cdfrac%7B70%7D%7B100%7D%5Ctimes%201600%5C%5C%5C%5Cx%3D1120)
Hence, 1120 audiences were not teenagers.

Answer:
The equation for the relationship is
.
Step-by-step explanation:
Given that point
is part of a direct relationship. That is:
![y \propto x](https://tex.z-dn.net/?f=y%20%5Cpropto%20x)
(1)
Where
is the proportionality constant.
If we know that
and
, then the proportionality constant is:
![k = \frac{y}{x}](https://tex.z-dn.net/?f=k%20%3D%20%5Cfrac%7By%7D%7Bx%7D)
![k = \frac{21}{6}](https://tex.z-dn.net/?f=k%20%3D%20%5Cfrac%7B21%7D%7B6%7D)
![k = \frac{7}{2}](https://tex.z-dn.net/?f=k%20%3D%20%5Cfrac%7B7%7D%7B2%7D)
Lastly, the equation for the relationship is
.
