So if you take a look at line five, you will see that we have two double variables, hours and age, because I am using the same example of hours in a parking lot and the age of a person. Hours is 3.1 and age is 14.8. So let's take a look at line seven. It says I parked for this many hours, so I got this many hours charged.
