Serhud [2]

Answer:

The dose in milligrams of a 6-year-old child is 60.

Step-by-step explanation:

The formula is:

$C = \frac{a}{(a+ 12)}A$

We know that

A= adult dosage in milligrams=180 milligrams

a = age of the child = 6 years-old

So the child’s dosage in milligrams is:

$C = \frac{6}{(6+12)}*180$

$C = \frac{1}{(3)}*180$

$C = \frac{180}{(3)}$

$C = 60\ milligrams$
