how much active ingredient is needed to compound 18 lollipops if the formula is 5% active ingredient, 168g sugar,60ml Karo syrup (weighs 84g),60ml water. each lollipop should have 5% active ingredient
(Junk+active ingred)=total mass
but active ingredient= .05 total mass
so, 168+84+60+.05totalmass=total mass
.95 total mass=168+84+60
now solve for total mass, and active ingredient.
