Answer:
250 adult tickets
Explanation:
s = number of student tickets
a = number of adult tickets
s = a - 56 ==> 56 fewer student tickets sold than adult tickets
s + a = 444 ==> 444 total tickets were sold
(a - 56) + a = 444 ==> plug in a - 56 for s to solve for one variable
a - 56 + a = 444
a + a - 56 = 444 ==> combine like terms
2a - 56 = 444
2a = 500 ==> add 56 on both sides
a = 250 adult tickets
s:
s + a = 444
s + 250 = 444 ==> plug in 250 for a
s = 194 student tickets sold
a - s = 56
250 - 194 = 56 √
Hence, the difference between the number of student and adult tickets is 56.
