Question

A total of 324 tickets were sold for the school play. They were either adult tickets or student tickets. The number of student tickets sold was two times the number of adult tickets sold. How many adult tickets were sold?

Answer 1

A + s = 324
s = 2a

a + 2a = 324
3a = 324
a = 324/3
a = 108

s = 2a
s = 2(108)
s = 216

so there were 108 adult tickets (a) and 216 student tickets (s)
