Question

What is the prescribed dosage for a 4 yr old child, if the adult dosage is 180 milligram

Answer 1

In order to calculate the child's dosage, let's use the value of n = 4 and M = 180 in the formula, then we calculate the value of D:

`\begin{gathered} D=(n)/(n+12)\cdot M \\ D=(4)/(4+12)\cdot180 \\ D=(4)/(16)\cdot180 \\ D=(1)/(4)\cdot180 \\ D=(180)/(4) \\ D=45 \end{gathered}`

So the child's dosage is 45 milligrams.
