  2. (a)20x8000=160000
    160000x98%=156800//

    (b)25-20=5
    5/20x100%=25%

    (c) (8000x25)xX%

    (d)(1000-4x)-2000x=1000-2004x

  5. a) 20 X 8000 = 160 000
    100 - 2 = 98
    98% X 160 000 = 156 800

    b) 25-20=5
    5/20 X 100 = 25%

    c)
    x% X (25X8000)
    = x% X 200 000
    = x X 2000
    = 2000x
    Ans: $(2000x)

    d)
    2/3 X (1500-6x)
    = 2 X (500-2x)
    = 1000 - 4x
    Total Cost in 2006 -> $(1000-4x)
    Total Cost in 2005 -> $(2000x)
    Increase-> (1000-4x) - (2000x) = 1000-2004x
