Difficult to understand Girls

Girl: Do you smoke?
Boy : Yes
Girl: How many packs a day?
Boy : 3 packs
Girl: How much per pack
Boy : $10.00
Girl: And how long have you been smoking?
Boy : 15 years
Girl: So 1 pack cost $10.00 and you have 3 packs a day which puts your spending each month at $900. In one year, it would be $10,800 correct?
Boy : Correct
Girl: If in 1 year you spend $10,800 not accounting for inflation, the past 15 years puts your spending at $162,000 correct?
Boy : Correct
Girl: Do you know that if you hadn't smoked, that money could have been put in a step-up interest savings account and after accounting for compound interest for the past 15 years, you could have now bought a Ferrari?

Boy : Do you smoke?
Girl: No
Boy : Where's your Ferrari then?
