Ticket sales. stacey is selling tickets to the school play. the tickets are $8 for adults and $4 for children. she sells twice as many adult tickets as children's tickets and brings in a total of $120. how many of each kind of ticket did she sell?

Respuesta :

Karollina
Adult tickets + kids tickets = 120$
Y represents kids tickets
Z represents adult tickets

Z = twice kids tickets = 2Y

In ecuation:

Z + Y = 120$

Replace Z with 2Y

2Y + Y = 120 $

3Y= 120 / divided by 3

Y = 40$

You know the cost for 1 kid ticket

40 : 4 = 10 kids tickets sold

Z = 2x 40= 80$ for adult tickets

80:8 = 10 adult tickets sold
