Question

tickets to the theater cost $12 for adults and $9 for children. A group of 15 adults and children are attending the theater. If the total cost was $153, how many adults and how many children went?

Answer 1

Answer:

6 Adults

9 Children

Step-by-step explanation:

-12(X+Y) = 15

12x+9y= 153

X+9= 15

12x -12y = -180

12x+9y = 153

X+9= 15

-9 -9

X= 6  

-3y = -27

Y= 9

Answer 2

Answer:

Can be either 6 adult tickets and 9 children tickets or 9 adult tickets and 5 children tickets
