A firm wants to hire one of two applicants, R or S for a short-term job. R has more experience and, if hired, would be paid 15 percent more per hour than S. If it takes S 1.5 times as long to do the job as it takes R, how many hours would S require to do the job?

(1)The firm would pay S a total of $360 to do the job.
(2)It would take R 40 hours to do the job and the firm would pay R $6.9 per hour.

答案是B

想請問B答案能求出R但要怎麼算出S呢???



因為不是OG或PP的題目所以不知如何編號
請見諒

85% Sr =Ss
1.5 Tr=Ts
求 Ts? 上班時間

選項二Tr=40
1.5 X 40=Ts
所以Ts就是60小時
