Question 1028922
Hi there,
Make student tickets = x
Make non-student tickets = y
x + y = 350....(1)
x + 2y = 450...(2)
Subtract Eq(1) from Eq(2)
....y = 100
Substitute y = 100 in
Eq(1)
x + y = 350......(1)
x + 100 = 350
x = 350 - 100
x = 250
250 Student tickets were sold
100 non-Student tickets were sold.
Hope this helps :-)
