Question 842196: a beaker contains 30 oz of an acid solution. A second beaker contains 35 oz of an acid solution, which has a concentration which is twice the concentration of the acid solution in the first beaker. The contents of these 2 beakers are poured into a third beaker. The acid solution in this 3rd beaker has a concentration of 17%. Find the concentrations of the acid solutions in the first 2 containers
