Problema Solution
A medication contains 9 mg of active ingredients for every 1 mg of inert ingredients. How much of each kind of ingredient would be contained in a single 250-mg caplet?
Answer provided by our tutors
Let
x = mg of inert ingredient
9x = mg of active ingredients
x + 9x = 250
10x = 250 divide both sides by 10
x = 250/10
x = 25 mg
9*25 = 225 mg
25 mg of the inert ingredients and 225 mg of the active ingredients are contained in a single 250 mg caplet.
