For this problem, we need to do a rule of three, like this:
[tex]\begin{gathered} 125\text{ MG medicine }\to\text{ 150 LB} \\ \text{? MG medicine }\to\text{ 142 LB} \end{gathered}[/tex]And the calculation would be:
[tex]142\text{ LB}\cdot\frac{125\text{ MG medicine}}{150\text{ LB}}=118.33\text{ MG medicine.}[/tex]The appropriate medication for this patient is 118.33 MG.
