The total quantity of drugs needed to be supplied for the number of days given would be =9 bottles plus 2 tablets.
How to determine the dosage needed?
To calculate the total dosage needed, the following steps should be taken as follows:
The number of tablets needed a day = 2 × 4 = 8 tablets
The number of tablets in a bottle = 26
The number of days needed for the drugs to be taken = 30days
If a day = 8 tablets
30 days = 30×8 = 240tablets
Therefore the number of bottles to be supplied = 240/26 = 9 bottles 2 additional tablets.
