Answer:
![f(x)=6.50x+48.00](https://tex.z-dn.net/?f=f%28x%29%3D6.50x%2B48.00)
Step-by-step explanation:
Let
x ----> the number of adult tickets
f(x) ----> amount of money collected
To find the amount collected multiply the number of adult tickets by the cost and multiply the number of student tickets by the cost, and then sum the two quantities
The linear equation that represent this problem is
![f(x)=6.50x+4.00(12)](https://tex.z-dn.net/?f=f%28x%29%3D6.50x%2B4.00%2812%29)
![f(x)=6.50x+48.00](https://tex.z-dn.net/?f=f%28x%29%3D6.50x%2B48.00)
Answer:
3.
Step-by-step explanation:
For this question, you just have to pick apart what "no less than" means. If I say I can have no less than 2 apples to eat, that's me saying that that's the minimum number I can have, but 2 apples is also still fine. In this case, that minimum is 50 but we can still have over 50. So, 6x+4 can be greater than or equal to 50.
Answer: x<12
Step-by-step explanation:
5(x+5)<85
5x+25<85
5x<85-25
5x<60
X<60/5
X<12
