Safari Adventure Theme Park is a selfguided theme park in which people drive through a park filled with African wildlife. They are given a map and a written guide to the wildlife of the park. They charge $20 per car plus $2.00 per person in the car. The number of people per car can be represented by the random variable X which has a mean value _X= 3.2, and a variance ²_x= 1.4. What is the variance of the total amount of money per car that is collected entering the park?
