X = child’s dosage per ml
A = child’s age
N = normal adult dosage in ml

(a) 2 year old
(b) 8 year old
(c) 14 year old
(d) 22 year old

I am trying to teach her this form of Maths, this is a new concept for her, she has worked out the following, I am Concerned I am leading Her up the wrong path, was just looking for clarification please. Sorry I did omit that the answer needed to be to the nearest two decimal places.
(a) A = 2; x = 2/2+12 x N = 0.07 ml would be the dose
(b) A = 8; X = 8/8+12 x N = 0.4 ml would be the dose
(c) A = 14; X = 14/14+12 x N = 0.54 ml would be the dose
(d)A = 22; X = 22/22+12 X N = 0.65 ml would be the dose

I appreciate everyone‘s time.
 
You need to also give us the formula.

You do realize that 2/2, 8/8, 14/14 and 22/22 all equal to 1?

So in all 4 cases you have 1 + 12 X N. Now this equation depends on N, which is the Normal adult dosage. But you did not give us this information.

Shouldn't the dosage be lower for a 2 year old than a 22 year old? But you still use N in all the equation.

If you want help from this forum then you must give us the exact wording of the complete problem, please!
