In a stadium, 1,000 tickets were sold. Children’s tickets cost $2.50 each and adults’ tickets cost $5.00 each. The revenue collected for the game was $4,000. Ho

Question

a. Children’s tickets = 400 and Adults’ tickets = 300
b. Children’s tickets = 700 and Adults’ tickets = 600
c. Children’s tickets = 200 and Adults’ tickets = 300
d. Children’s tickets = 400 and Adults’ tickets = 600

Answer 1

The answer is d. Children's tickets = 400 and Adult's tickets = 600

Work:

Let Children's tickets be x and let adult's tickets be y then:

x+y=1000

also,

2.5x+5y=4000

and you can solve this system of two equations with two variables either by: Graphing, Substitution, or Elimination to get

x=400 and

y=600

(400,600)
