PROBLEM A:

Ten years ago Susan’s uncle was three times older than she was. Now Susan’s uncle is one year older than twice her age. How old is Susan now?

PROBLEM B:

You are a supervisor in a hospital in charge of nurse’s shifts. You have 29 weekend shifts and 61 weekday shifts to distribute among three nursing stations (trauma, pediatric care, and maternity). The maternity station needs twice as many shifts as the trauma station on weekdays, but the same number of shifts on weekends. To cover necessary tasks, the pediatric care station needs one more shift than the trauma station on weekdays but four less shifts than trauma on weekends.
