Since the dosage is 2 tables, 3 times a day, so the number of tablets needed per day is 3 * 2 = 6 tablets.
The number of days required is 14, so the total number of tablets needed is 14 * 6 = 84.
If each bottle has 15 tablets, so the number of bottles required is:

So we will need 5 full bottles.
These 5 bottles can hold 5 * 15 = 75 tablets. To reach 84 tablets, we also need 84 - 75 = 9 additional tablets.
