    Section A = 25,000 seats

    Section B = 14,600 seats

    Section C = 10,400 seats

    Step-by-step explanation:

    Total Seats = 50,000

    Seats in Section A cost = $30

    Seats in Section B cost = $24

    Seats in Section C cost = $18

    Total sales from the event = $1,287,600

    No. of Seats in section A = No. seats in Section B + No. seats in Section C

    A = B + C

    or, 2A = 50,000

    A = 25,000 seats @ $30/seat = $750,000

    B + C = 25,000

    24B + 18C = 537,600

    24B + 18 (25,000 - B) = 537,600

    24B + 450,000 - 18B = 537,600

    6B = 87600

    B = 14,600

    C = 10,400

    Hence;

    A = 25,000 seats

    B = 14,600 seats

    C = 10,400 seats
