Answer:
Option A , C ,D
Step-by-step explanation:
A nonrefundable deposit required for the day-long program = $50
Charge per person = $4.50
Let us suppose the number of students is s
So, Charge for s students = $4.50s
Let c denotes the total cost
So, total cost : ![c=50+4.50s](https://tex.z-dn.net/?f=c%3D50%2B4.50s)
So, Option A is correct : The linear model is f(s) = 4.5s + 50.
Total cost : ![c=50+4.50s](https://tex.z-dn.net/?f=c%3D50%2B4.50s)
We are given that total students are 24
Substitute s = 0
So, ![c=50](https://tex.z-dn.net/?f=c%3D50)
Substitute s = 24
![c=50+4.50(24)](https://tex.z-dn.net/?f=c%3D50%2B4.50%2824%29)
![c=158](https://tex.z-dn.net/?f=c%3D158)
So, Option C and D is also correct.
C. The domain is {x| 0 ≤ x ≤ 24}
D .The range is {y| 50 ≤ y ≤ 158}

The graph is discrete .
So, Option E is incorrect.
