    735.64

    Step-by-step explanation:

    6% of 860 = 51.6

    860-51.6 = 808.4

    9% of 808.4 = 72.756

    808.4 - 72.756 = 735.644

    Step-by-step explanation:

    Increased amount = 106% of 860 = 1.06 * 860 = 911.60

    Amount after decrease = 91% of 911.60 = 0.91 * 911.60 = 829.556 = 829.56
