Answer provided by our tutors
let
a = the number of adult tickets sold
s = the number of student tickets sold
on opening night 400 tickets were sold:
a + s = 400
a total of 1,580$ was made from the sale:
5a + 3.50s = 1580
by solving the system of equations:
a + s = 400
5a + 3.50s = 1580
we find:
a = 120 adult tickets
s = 280 student tickets
