Answer:
65 adult tickets and 135 student tickets were sold.
Step-by-step explanation:
4s + 6a = 930
s + a = 200
s = -a + 200
4(-a + 200) + 6a = 930
-4a + 800 + 6a = 930
2a + 800 = 930
2a = 130
a = 65
There were 65 adult tickets sold.
200 - 65 = 135
There were 135 student tickets sold.
Check:
4(135) + 6(65) = 930
540 + 390 = 930
930 = 930
