Solve alcohol systems to find the right solution. The interactive allows pupils to manipulate the amount of a solution and displays the total amount in a mixture. Individuals determine the amount of each solution needed to make 15 liters of particular percent solution. They then determine the system of equations they can use to solve the problem algebraically.

Instructional Ideas

• Have the scholars create a table of values for the different amounts of each solution and the amount of alcohol in the final solution

Classroom Considerations

• The class should know how to create linear equations in two variables
• Requires signing up for a free CK-12 account

Pros

• Populates the correct answer when the user gives the wrong one
• The supplemental material contains additional examples

Cons

• None
