last year a worker saved 10 % of her annual salary . this year , she made 10 % more money than last year and she saved 12 % of her salary . the amount she saved this year was what percent of the amount she saved last year ?
"let x be the worker ' s salary last year . last year , she saved 0.1 x . this year , she saved 0.12 ( 1.1 x ) = 0.132 x 0.132 x / 0.1 x = 132 % the answer is d ."
multiply(const_100, divide(10, multiply(add(10, const_100), divide(12, const_100))))
