    This problem can be solved purely by analysis.

    y is only 80% of 90% of x, therefore:

    y = 0.80 * (0.90 * x)

    y = 0.72 x - - - > 1

    z is 125% of 130% of y, therefore:

    z = 1.25 * (1.30 * y)

    z = 1.625 y - - - > 2

    Therefore combining 1 and 2:

    z = 1.625 * (0.72 x)

    z = 1.17 x

    So z is 117% of x.
