One weekend, 600 tickets were sold to a carnival for a total of $2400. If an adult's ticket costs $6 and a child's ticket costs $4, how many adults and how many children went to the carnival ?

Respuesta :

Answer:

adults : 0  children: 600

Step-by-step explanation:

x + y = 600

6x＋4y = 2400

4×(x + y = 600) = 4x＋4y = 2400

(6x＋4y = 2400) － (4x＋4y = 2400) = x=0

so y=600
