if sharon ' s weekly salary increased by 20 percent , she would earn $ 600 per week . if instead , her weekly salary were to increase by 15 percent , how much would she earn per week ?
"soln : - ( 600 / 120 ) 115 = 575 in this case long division does not take much time . ( 5 / 1 ) 115 = rs . 575 answer : a"
add(divide(600, add(const_1, divide(20, const_100))), multiply(divide(15, const_100), divide(600, add(const_1, divide(20, const_100)))))
