The theater charges $5.5 per ticket per person of any age group.
Your expression would not have $5.5c or $5.5a as they have a price for only one variable.
Your expression would be 5.5(a+c).
Your first option is the correct one.
Answer:
h=7
Step-by-step explanation:
We want to solve the equation:
![\frac{1}{h-5}+\frac{2}{h+5}=\frac{16}{h^2-25}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7Bh-5%7D%2B%5Cfrac%7B2%7D%7Bh%2B5%7D%3D%5Cfrac%7B16%7D%7Bh%5E2-25%7D)
We multiply through by the LCM: ![h^2-25=(h+5)(h-5)](https://tex.z-dn.net/?f=h%5E2-25%3D%28h%2B5%29%28h-5%29)
![(h^2-25*\frac{1}{h-5}+(h^2-25)*\frac{2}{h+5}=\frac{16}{h^2-25} \times(h^2-25)](https://tex.z-dn.net/?f=%28h%5E2-25%2A%5Cfrac%7B1%7D%7Bh-5%7D%2B%28h%5E2-25%29%2A%5Cfrac%7B2%7D%7Bh%2B5%7D%3D%5Cfrac%7B16%7D%7Bh%5E2-25%7D%20%20%20%5Ctimes%28h%5E2-25%29)
Simplify to get:
![h+5+2(h-5)=16](https://tex.z-dn.net/?f=h%2B5%2B2%28h-5%29%3D16)
We expand to get:
![h+5+2h-10=16](https://tex.z-dn.net/?f=h%2B5%2B2h-10%3D16)
![h+2h=16+10-5](https://tex.z-dn.net/?f=h%2B2h%3D16%2B10-5)
![3h=21](https://tex.z-dn.net/?f=3h%3D21)
h=7
