3.1: Use a Problem-Solving Strategy
3.2: Solve Percent Applications
We will solve percent equations using the methods we used to solve equations with fractions or decimals. Without the tools of algebra, the best method available to solve percent problems was by setting them up as proportions. Now as an algebra student, you can just translate English sentences into algebraic equations and then solve the equations.
3.3: Solve Mixture Applications
In mixture problems, we will have two or more items with different values to combine together. The mixture model is used by grocers and bartenders to make sure they set fair prices for the products they sell. Many other professionals, like chemists, investment bankers, and landscapers also use the mixture model.
3.4: Triangles, Rectangles, and the Pythagorean Theorem
3.5: Solve Uniform Motion Applications
3.6: Solve Applications with Linear Inequalities
