Answer:
75 tablets
Step-by-step explanation:
Firstly
3 tablets twice daily means "take 3 tablets at a time" 2 times in a day. So, that is 3 * 2 = 6tablets per day
This is for 10 days, so total of 6 * 10 = 60 tablets
Then, 1 tablet per day for 15 days, that is 1 * 15 = 15 tablets
Therefore, in total 60 + 15 tablets needs to be dispensed, 75
