Adult tickets for a play cost $19 and child tickets cost $17. If there were 36 people at a performance and the theatre collected $646 from ticket sales, how many children attended the play?

  • Math -

    A. Using algebra
    Let
    A=number of adults who attended, then
    36-A = number of children who attended
    19A + 17(36-A) = 646
    Solve for A.

    B. Using arithmetic
    If only adults went, ticket sales would have collected 36*19=$684
    For every child who went, sales would reduce by $2.
    So number of children=(684-646)/2=19

    19
