Answer:
1,296 students attended the fall play.
Explanation:
Let the amount of students = s
Let the amount of adults = a
Three times the adults: 3a
150 fewer than three times the adults:3a-150
amount of students = 150 fewer than three times the adults: s=3a-150
We also know that a+s=1778. Let's sub in the value for s that we got above:
a+s=1778
a+3a-150=1778
4a=1928
a=482
a+s=1778
482+s=1778
s=1296
