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 :
So, Option A is correct : The linear model is f(s) = 4.5s + 50.
Total cost :
We are given that total students are 24
Substitute s = 0
So,
Substitute s = 24
So, Option C and D is also correct.
C. The domain is {x| 0 ≤ x ≤ 24}
D .The range is {y| 50 ≤ y ≤ 158}
Refer the attached figure
The graph is discrete .
So, Option E is incorrect.
