Answer:
55 adult tickets were sold on Friday.
Step-by-step explanation:
A linear system will be used to model the system.
Let c be the number of child tickets and a be the number of adult tickets
Then according to given statements
![a+c = 133\ \ \ \ Eqn\ 1\\9.50a+5.20c = 928.10\ \ \ Eqn\ 2](https://tex.z-dn.net/?f=a%2Bc%20%3D%20133%5C%20%5C%20%5C%20%5C%20Eqn%5C%201%5C%5C9.50a%2B5.20c%20%3D%20928.10%5C%20%5C%20%5C%20Eqn%5C%202)
From equation 1
![a = 133-c](https://tex.z-dn.net/?f=a%20%3D%20133-c)
Putting this in equation 2
![9.50(133-c)+5.20c = 928.10\\1263.5-9.50c+5.20c=928.10\\1263.5-4.3c = 928.10\\-4.3c = 928.10-1263.5\\-4.3c=-335.4\\\frac{-4.3c}{-4.3} = \frac{-335.4}{-4.3}\\c = 78](https://tex.z-dn.net/?f=9.50%28133-c%29%2B5.20c%20%3D%20928.10%5C%5C1263.5-9.50c%2B5.20c%3D928.10%5C%5C1263.5-4.3c%20%3D%20928.10%5C%5C-4.3c%20%3D%20928.10-1263.5%5C%5C-4.3c%3D-335.4%5C%5C%5Cfrac%7B-4.3c%7D%7B-4.3%7D%20%3D%20%5Cfrac%7B-335.4%7D%7B-4.3%7D%5C%5Cc%20%3D%2078)
Putting c = 78 in equation 1
![a+78 = 133\\a = 133-78\\a = 55](https://tex.z-dn.net/?f=a%2B78%20%3D%20133%5C%5Ca%20%3D%20133-78%5C%5Ca%20%3D%2055)
Hence,
55 adult tickets were sold on Friday.
Negative because if you take away from a negative, your just making it smaller... hope this helps!
Answer:
Option C is correct.
Best financial approach: pay off debts, save for an emergency, save for retirement.
Step-by-step explanation:
It is better to pay off the debts and then the rest of the money must be kept safe for the emergency because it is not necessary that you will have an emergency condition, it can take place or cannot take place. Then, when these two criteria are full filled then the rest of the money should be kept for the retirement.
Therefore, for the best financial approach :
![\text{pay off debt} \rightarrow \text{save for an emergency} \rightarrow \text{save for retirement}](https://tex.z-dn.net/?f=%5Ctext%7Bpay%20off%20debt%7D%20%5Crightarrow%20%5Ctext%7Bsave%20for%20an%20emergency%7D%20%5Crightarrow%20%5Ctext%7Bsave%20for%20retirement%7D)
