Lesson Summary:

In this lesson, we learn how to solve percent mixture problems using one variable by figuring out how much water should be added to a container of juice that is 70% juice to get a diluted mixture that is only 60% juice. By setting up an equation that represents the amount of pure juice in each container, we can solve for the variable, which in this case is the amount of water to be added. The solution is checked to make sure the final amount of pure juice is the same in both containers, and we discover that adding 5 cups of water is the solution to the given problem.
