Answer:

The number of adults is [tex]15\ adults[/tex]

The number of children is [tex]315\ adults[/tex]

Step-by-step explanation:

Let

c-----> the number of children

a-----> the number of adults

we know that

[tex]a+c=330[/tex] ------> equation A

[tex]c=21a[/tex] ------> equation B

substitute equation B in equation A and solve for c

[tex]a+21a=330[/tex]

[tex]22a=330[/tex]

[tex]a=15\ adults[/tex]

Find the number of children c

[tex]c=21a[/tex]

[tex]c=21(15)=315\ children[/tex]

therefore

The number of adults is [tex]15\ adults[/tex]

The number of children is [tex]315\ adults[/tex]

MrRoyal

The system of equations is c = 21a and a + c = 330

To answer this question, we make use of the following representations

  • a represents adults
  • c represents children

From the question, we have:

[tex]c = 21a[/tex] --- the relationship between the number of children and adults

[tex]a + c =330[/tex] --- the total number of people

Hence, the system of equations is c = 21a and a + c = 330
