Question

What is the prescribed dosage of a certain medicine for a 6 year old child if the adult dosage of the medicine is 180 milligram? Using formula C= _a__ . A a + 12

Answer 1

Child's dosage=60 milligram

Explanation:

The correct formula is below

C= a/(a+12) ∙ A

Where,

C = child’s dosage in milligrams

a = age of the child

A = adult dosage in milligrams

a=6 year old

A=180 milligrams

C= a/(a+12) ∙ A

=6/(6+12)*180

=6/18*180

=1/3*180

=60

Child's dosage in milligram=60 milligram
