What mathematical formula is mentioned for compounding suppositories?

B/(A-C+B)
A/(B+C-A)
C/(A+B-C)
D/(C+B-A)

The correct answer is: B/(A-C+B)

The correct formula for compounding suppositories is A/(C+B-A). This formula is used to calculate the amount of the active ingredient (A) needed, given the amount of the base (B) and the amount of the suppository (C). By dividing the product A by the sum of the base and the difference between the base and the suppository, you can accurately determine the quantity of the active ingredient required for compounding the suppository.
