The number of private investigators is expected to increase from 52,000 in 2006 to 61,000 in 2016. If there are 648,982 police officers in 2006, how many police officers must there be in 2016 to have a greater percent increase than that of private investigators?
Number of private investigators is expected to increase from 52000 to 61000. That is 61000-52000 = 9000. To get percentage of increase you have to divide increase (9000) with the number of investigators that were before the increase (52000). After that, you have to multiply the number of police officers with increase percentage and you will get by how much the number of officers have to rise. Sum that with number of officers before and you will get your result. Feel free to ask if you don't understand something!
