Total sales at carla's restaurant are up 2.7% over last year. if sales this year are $192,384, then what were the sales last year? (round your answer to the nearest dollar.)

Peter applied to an accounting firm and a consulting firm. he knows that 30% of similarly qualified applicants receive job offers from the accounting firm, while only 20% of similarly qualified applicants receive job offers from the consulting firm. assume that receiving an offer from one firm is independent of receiving an offer from the other. what is the probability that both firms offer peter a job?
