Alyssa is a chemist. She needs to prepare 12 ounces of a 9% hydrochloric acid solution. Find the amount of 4% and the amount of 12% solution she should mix to get this solution.
so far i only have:
let x = the amount of 4% solution.
let y = the amount of 12% solution.
my teacher told us this: "amount of solution * __% = amount of acid"
at this point, i am stuck as to where to even start.
