Answer:
60% of 500 is 300 and 40% of 500 is 200. 300-200=100
Step-by-step explanation:
Answer:
286 students attended
148 non students attended
Step-by-step explanation:
Given
![Tickets = 434](https://tex.z-dn.net/?f=Tickets%20%3D%20434)
![Students = \$4.00](https://tex.z-dn.net/?f=Students%20%3D%20%5C%244.00)
![Non-Students = \$6.00](https://tex.z-dn.net/?f=Non-Students%20%3D%20%5C%246.00)
![Total = \$2032.00](https://tex.z-dn.net/?f=Total%20%3D%20%5C%242032.00)
Solving (a): Number of students
Represent students with S and non students with N
So:
--- (1)
--- (2)
Make N the subject of formula in (1)
![N = 434 - S](https://tex.z-dn.net/?f=N%20%3D%20434%20-%20S)
Substitute 434 - S for N in (2)
![4S +6(434 - S) = 2032](https://tex.z-dn.net/?f=4S%20%2B6%28434%20-%20S%29%20%3D%202032)
Open Bracket
![4S + 2604 - 6S = 2032](https://tex.z-dn.net/?f=4S%20%2B%202604%20-%206S%20%3D%202032)
Collect Like Terms
![4S - 6S = 2032 - 2604](https://tex.z-dn.net/?f=4S%20-%206S%20%3D%202032%20-%202604)
![-2S = -572](https://tex.z-dn.net/?f=-2S%20%3D%20-572)
Divide through by -2
![S = 286](https://tex.z-dn.net/?f=S%20%3D%20286)
<em>Hence; 286 students attended</em>
Solving (b):
Recall that
![N = 434 - S](https://tex.z-dn.net/?f=N%20%3D%20434%20-%20S)
![N = 434 - 286](https://tex.z-dn.net/?f=N%20%3D%20434%20-%20286)
![N = 148](https://tex.z-dn.net/?f=N%20%3D%20148)
<em>148 non students attended</em>
