Answer:
350
Explanation:
Let "a" represent the number of adult tickets sold and "s" represent the number of student tickets sold. We can set up the following equation to represent the information given:
a + s = 627
s = a - 73
Substituting the second equation into the first equation gives us:
a + (a - 73) = 627
2a - 73 = 627
2a = 700
a = 350
Thus, there were 350 adult tickets sold.
