    Assume original price = x

    According to the question, x - (x * 0.15) = x - 30

    => x - x - 0.15x = - 30

    => - 0.15x = - 30

    => x = - 30/-0.15

    x = $200

    15% = $30

    1% = 30 : 15

    1% = $2

    100% = 2 x 100

    100% = $200

    Answer: The original price of the computer is $200.
