Question: Jordan has 2 children who wear diapers.  Each child requires 5 diaper changes per day.  Jordan's wife changes half of the diapers.  How many diapers does Jordan change per day?
Answer: 
Jordan has 2 children, each requiring 5 diaper changes per day, for a total of 5*2=10 diaper changes per day.
Jordan's wife changes half of the diapers, leaving Jordan to change the other half, for a total of 10/2=5 diaper changes per day that Jordan is responsible for.
