Kevin repairs phones at his job. At the beginning of the day, Kevin has 15 phones that need to be repaired. By the afternoon, Kevin has successfully repaired 3 of the 15 phones and a client has dropped off 6 more phones that need fixing. If a coworker of Kevin's offers to help him and fix half of the damaged phones, how many phones will each person need to repair?
Kevin begins the day with 15 phones and repairs 3 by the afternoon, so Kevin still has to repair 15 - 3 = <<15-3=12>>12 phones.
A client drops off 6 additional phones that require fixing, increasing the total to 12 + 6 = 18 phones.
If Kevin's coworker helps Kevin fix half of the phones, then each person needs to fix 18 / 2 = <<18/2=9>>9 phones.
