P and Q are the only two applicants qualified for a short-term research project that pays 360 dollars in total. Candidate P has more experience and, if hired, would be paid 50 percent more per hour than candidate Q would be paid. Candidate Q, if hired, would require 10 hours more than candidate P to do the job. Candidate P’s hourly wage is how many dollars greater than candidate Q’s hourly wage?  Choose the correct choice from the following answers
A) $3 B) $6 C) $9 D) $12 E) $15
Let Q's hourly wage be x, then P's hourly wage is 1.5x   Let T be the number of hours that Q needs, then P needs T-10 hours to do the job.   Since they both are paid an equal total amount of $360:   x*T=1.5x*(T-10)   T = 30 hours and Q's hourly wage is 360/30=
