Young's Rule for determining the amount of medicine dosage for a child is given by the formula:

where a is the child's age and d is the usual adult dosage in mg and c is the child dosage in mg.

Suppose the adult dosage of a particular medication is 10 times your age in mg. Use Young's Rule to convert the adult dosage to a child dosage.

1. State your age. If you don't want to provide your actual age, you can use the age of another adult in your life.
2. age 34
3. Calculate, "d", the adult dosage in mg. 500mg
4. Provide, "a", the age of a child between the ages of 2 and 12. 6
5. Calculate, "c", the child dosage in mg.
