Answer :
The dosage has been defined as the amount or the frequency of the medication to be given to an individual. A 112-pound weighing person must be given 203.21 mg of the prescribed medicine.
What is the unitary method to calculate dosage?
The unitary method is defined as the method that solves the problem by calculating the amount of the value of the single unit and then calculating further for the required amount of the value of the units needed.
The value derived from a single unit has been used to estimate the other values and amounts that use cross multiplication to estimate and calculate the values.
Given,
Dosage per kg = 4.00 mg
Weight of the person = 112 pound
At the first unit, the pound is converted into kilograms as:
one pound = 0.453592 kilograms
So, 112 pound = 50.8023 kilograms
If a one-kilogram weight gets 4.00 mg of the dosage of the medicine then 50.8023-kilogram weighing will get X amount of dosage.
Solving further as:
1 kg = 4.00 mg
50.8023 kg = 50.8023 × 4
= 203.21 mg
Therefore, a 112-pound person gets 203.21 mg of medication.
