## HSI.1 Linear Equations & Inequalities (A1)

### Wage War

How much should companies pay their employees? Students graph and solve systems of linear equations in order to examine the effects of wage levels on labor and consumer markets, and they discuss the possible pros and cons of increasing the minimum wage.

Topic: Linear, Quadratic, and Exponential Models (LE), Reasoning with Equations and Inequalities (REI)

### Datelines

What's an acceptable dating range? Students use linear equations and linear inequalities to examine the May-December romance, and ask whether the Half Plus Seven rule of thumb is a good one.

Topic: Building Functions (BF), Creating Equations (CED), Expressions and Equations (EE), Functions (F), Interpreting Functions (IF), Reasoning with Equations and Inequalities (REI)

### Financial Aid

How much more do graduates earn, and is college worth the cost? Students use systems of linear equations to compare different educational options.
