The pre-placed blocks draw the animation of the pouring of solution from the red container into the blue container. The red container contains salt water that is 15% salt by mass. The larger blue container contains 3 cups of salt water that is 40% salt by mass. How much of the salt water from the red container must be added to create a mixture that is 25% salt by mass? Edit the first block and set "amountRedSolution" to the correct number.
