who were in the group.

Respuesta :

Answer: children = 22

Adult = 11

Step-by-step explanation:

Let the number of adult be a

Since there were twice as many children as adults in the

group, the children can be represented by : 2 × a = 2a

We are further told that the group of 33 people attended a ball game. This means that :

adult + children = 33

a + 2a = 33

3a = 33

a = 11

11 adults are in the group

Since 11 adults are in the group, the number of children will be:

= 33 - 11

= 22
