Final answer:
If 2 tablets are taken in the morning and 1 at bedtime, there would be a 40-day supply in 120 tablets.
Step-by-step explanation:
To find the number of days supply in 120 tablets, we need to determine how many tablets are taken per day.
Since 2 tablets are taken in the morning and 1 tablet is taken at bedtime, the total number of tablets taken per day is 2 + 1 = 3 tablets.
Therefore, the number of days supply in 120 tablets would be 120 tablets / 3 tablets per day = 40 days.
