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?

Just think about the problem. If 19 people owned both a truck and a car, then those 19 are included in both groups so they are counted twice.
