Lesson Summary:

In this lesson, we learn how to solve a mixture problem by finding the right equation with variables. Using a simple drawing of two vats, we break down the cost and quantity of each ingredient, and then combine them into a bigger mix. By setting up an equation with the total cost of each ingredient, we can solve for the variable that represents the unknown quantity. Checking our answer at the end, we learn how to make sure we've arrived at the correct solution.
