if sharon ' s weekly salary increased by 16 percent , she would earn $ 406 per week . if instead , her weekly salary were to increase by 20 percent , how much would she earn per week ?
"( 406 / 116 ) 120 = 420 in this case long division does not take much time . ( 406 / 116 ) = 3.5 35 * 12 = 420 ( 350 + 70 ) answer a"
add(divide(406, add(const_1, divide(16, const_100))), multiply(divide(20, const_100), divide(406, add(const_1, divide(16, const_100)))))
