Each week, Harry is paid x dollars per hour for the first 30 hours and 1.5x dollars for each additional hour worked that week. Each week, Annie is paid x dollars per hour for the first 40 hours and 2x dollars for each additional hour worked that week. Last week Annie worked a total of 50 hours. If Harry and Annie were paid the same amount last week, how many hours did Harry work last week?
Choose the correct option:
A) 40
B) 45
C) 50
D) 55
E) 60
Annie earned 40x + 10(2x) = 60x   Let H be the number of hours that Harry worked.   Harry earned 30x + 1.5x(H-30) = 60x   (1.5x)(H) = 75x   H = 50 hours   The answer is 50.
