    how many tickets do i have to sell the first day if i sell ten less then the previous day

    that makes no sense. There is no previous day to the first day.

  • math - ,

    Monday you sold x tickets
    Tuesday you sold x-10
    wedn ... x-20
    thu ... x-30
    frid ...x-40

    x + x-10 + x-20 + x-30 + x-40 = 200
    5x - 100 = 200
    x = 60

    On the first day you had to sell 60 tickets.

    check:
    What is 60+50+40+30+20 ?
