the theatre charges $9 for each adult ticket and $6 for each child ticket. the theatre sold 144 tickets for the first showing of
the new release. the total money collected from ticket sales for that show was $1164. write a system of equations that could be used to find the number of child tickets and the number of adult tickets sold, and solve the system algebraically.
X=number of adult tickets y=number of child tickets I suggest this system of equations: x+y=144 9x+6y=1164 we can solve this system of equations by substitution method. x=144-y
