A chemist has 500 ml of a 30% acid solution. She adds x milliliters of a 10% acid solution. Which statement is true about the graph of the function that represents the concentration of the final solution?
Let y be concentration of the final solution: y = (0.1x + 0.3(500))/(500 + x) y = (0.1x + 150) / (500 + x) The numerator contains the total amount of acid and the denominator contains the volume of the solution.
