Question

the first screening of the latest movie had a box office take of $1,938. Adults pay 7.50 and children 4.50. there were four times as many children as adults. how many tickets sold were children and how many were adult?

Answer 1

7.50a + 4.50c = 1938
c = 4a

7.50a + 4.50(4a) = 1938
7.50a + 18a = 1938
25.5a = 1938
a = 1938/25.5
a = 76

c = 4a
c = 4(76)
c = 304

so there were 76 adult tickets (a) sold and 304 children tickets (c) sold
