A school drama department sells 40 more student tickets than adult tickets. Charging $8 for adult tickets and $6 for student tic

Butoxors [25]

Answer:

Adults = x

Students = y = x + 40. 40 more student than adult

Adult = $8, Student = $6

Total for Adults = 8*x = 8x

Total for students = 6*y = 6y

Total = $1920

8x + 6y = 1920

Hence system of equations are:

y = x + 40

8x + 6y = 1920
