A total of 430 tickets were sold for the school play . They were either adult tickets or student tickets . There were 70 fewer s

Maurinko [17]

So first we assume that half is adult and have is student.

So
215 adult 215 student

Now since it said they were 70 less student tickets than adult tickets we subtract 70.
215 - 70 = 145

Now we add the 70 we subtracted from student tickets to the adult tickets.
215 + 70 = 285

So there were
285 adult tickets sold and 145 student tickets sold
