Answer provided by our tutors
let
a = the number of adult tickets sold
s = the number of student tickets sold
Mark sold 500 tickets for the school play:
a + s = 500
Student tickets cost $2 and adult tickets cost $3. Marks sales totaled $1271:
3a + 2s = 1271
by solving the system of equations:
a + s = 500
3a + 2s = 1271
we find
a = 271 adult tickets
s = 229 student tickets
