So let's get started. We want to figure out how many total tablets are being taken each day. Once we know that, we can multiply that number by 10 since we want a 10-day-supply. The question states that the sig calls for 2 tablets, 3 times daily. 2 X 3 = 6 tablets per day. Next, we multiply 6 by 10 (days) which equals #60 tablets are needed. Finally, we subtract 16 ("On Hand") from 60 which equals 44. So we need an additional 44 tablets to fill the entirety of this prescription.
