A.100

B.400

C.500

D.600​

Answer 1

Answer is D. 600 adults

Answer 2

600 adults and 400 children attended the opening night's show

Let x represent the number of children and y represent the number of adult.

Since 1000 seat auditorium was sold out!, hence:

x + y = 1000   (1)

they had $3400. Hence:

2.5x + 4y = 3400    (2)

Solving equations 1 and 2 simultaneously gives:

x = 400, y = 600

600 adults and 400 children attended the opening night's show.
