Two expressions for calculating the drug dose for young children are:
(2t^3 + t^2 t)a / 48t^2 24t and (3t^2 2t)a / 3t^2 + 34t  24
where t is the age of the child in years and a is the adult dose. If the adult dose for a pain killing drug is 250mg, then what is the dose to the nearest unit for:
a. a child of one year
b. an eight month of child

Since you provide two expressions, and they are not the same, how do we tell which to use?
The first is a(t+1)/24
The second is at/(t+12)
Just plug in
250 for a and
1 or 2/3 for t
to get the desired child doses.
