  2. 100%-2%=98%
    98% x 20¢=19.6¢
    19.6¢ x 8000 =156800¢=$1568(a)
    25¢-20¢=5¢
    5/20 x 100% =25%(b)
    100%-x% =(100-x)%
    (100-x)% x 25¢ =(2500-25x)¢
    (2500-25x)¢ x 8000=(20000000-200000x)¢=$(200000-2000x)(c)
    $2/3(1500-6x) - $(200000-2000x) =$1000-$4x-$200000+$2000x=$1996x-$199000= $(1996x-199000)(d)
