Kiara adds an 80% acid solution to 5 milliliters of solution that is 20% acid. The function that represents the percent of acid in the resulting solution is f(x) = __5(0.20) + x(0.80) 5 + x , where x is the amount of 80% solution added. How much 80% solution should be added to create a solution that is 50% acid?
