No of cigarettes

15 years of age = 14600 cigarettes  

19 years of age = 43800 cigarettes  

25 years of age = 87600 cigarettes

50 years of age = 270100 cigarettes

No of packs

15 years of age = 730 packs

19 years of age = 2190 packs

25 years of age = 4380 packs

50 years of age = 13505 packs

Step-by-step explanation:

Jason started smoking when he turned 13 years of age.

Average smoking per day = 1 pack = 20 cigarettes

No of Cigarettes consumed

       No of days = 730 days

       No of cigarettes = 730 * 20 = 14600 cigarettes  

        No of days  = 6*365 = 2190 days

        No of cigarettes = 2190*20 = 43800 cigarettes  

        No of days  = 12*365 = 4380 days

        No of cigarettes = 4380*20   = 87600 cigarettes

        No of days = 37*365  = 13505

        No of cigarettes = 13505*20 = 270100 cigarettes

No of packs

15 years of age = 14600/20 = 730 packs

19 years of age = 2190 packs

25 years of age = 4380 packs

50 years of age = 13505 packs
