If the patient is taking 3 tablets daily, we divide 100 by 3 tabs daily and we come up with 33.
This means that the #100 tablets at the 3 tablets taken each day dosing, will last 33 days.
This prescription has a 33 days supply. As a sidebar, you never round up when you have a remainder. In this example, the remainder is .3 but we round down to 33, and never up to 34 because the .3 remainder would not exceed an additional day, making the days supply 34.
