Answer:options B and D are the correct answers.
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.
The function is defined by
C(x) = 30x
The values of x must be whole numbers. Therefore, the possible outputs for the defined function would be
B. 30 which means the cost for only one student.
D. 90 which means the total cost for 3 students.
Okay, so the equations would be:
x + 3y = 24
3y + 5x = 36
Imma use Substitution to solve this:
x = -3y + 24
3y + 5(-3y + 24) = 36
3y - 15y + 120 = 36
-12y + 120 = 36
-12y = -84
y = 7
x = -3(7) + 24
x = -21 + 24
x = 3
So the first number (x) would be 3 and the second number (y) would be 7.
