An event sold $608 worth of tickets. Adult tickets cost $11 and children’s tickets cost $6. If 68 tickets were sold, how many were adult tickets and how many were children’s tickets?

Respuesta :

Answer:

40 Adult tickets and 28 childrens tickets

Step-by-step explanation:

11a+6c=608

a+c=68

a=68-c

11(68-c)+6c=608

748-11c+6c=608

748-5c=608

-5c=-140

c=28

a=40
