The cost for an upcoming field trip is $30 per student. The cost of the trip C, in dollars, is a function of the number of students x. Select all the possible outputs for the function defined by C(x)=30x.

B. 30

D. 90

Step-by-step explanation:

The cost for an upcoming field trip is $30 per student. The cost of the field trip C, in dollars, is a function of the number of students x. Select all the possible outputs for the function defined by c(x) = 30x. A. 20 B. 30 C. 50 D. 90 E. 100

Given function:

C(x) = 30x

Where,

x = number of students

A. 20

C(x) = 30x

20 = 30x

x = 20/30

= 0.67

x = 0.67 student

B. 30

C(x) = 30x

30 = 30x

x = 30/30

x = 1 student

C. 50

C(x) = 30x

50 = 30x

x = 50/30

x = 1.67 students

D. 90

C(x) = 30x

90 = 30x

x = 90/30

x = 3 students

E. 100

C(x) = 30x

100 = 30x

x = 100/30

= 3.33

x = 3.33 students

Number of students, x should be an whole number

The possible for the function are

B. 30

D. 90

answer: just subtact the units and then add the non negative : happy to
