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.
Hey there! :)
Since 0.8 is less than 1, you can cross out every fraction greater than 1. If the numerator(top number) is greater than the denominator(bottom number), it is greater than 1
_____________________________________________________________
You can cross out 12/7 because it is greater than 1.
That leaves you with 3 choices.
_____________________________________________________________
Now, divide the numerator by the denominator to change all 3 fraction to decimal.
_____________________________________________________________
7 ÷ 8 = 0.875
3/6 = 0.5
4/5 = 0.8
A. 12/7 x
B. 7/8 x
C. 3/6 x
D. 4/5 <span>✔
Your answer is the last choice.
Hope this helps :)</span>
