gurly691	Posted - 07/09/2011 : 12:23:52 A car dealership interviewed every driver who came onto their lot on Tuesday. This produced the following results: there were 34 people who owned trucks and 59 people who owned cars. If 19 people owned both a truck and a car and 7 people owned neither, how many people were interviewed?
