How do municipal fines affect people with different incomes?

How do municipal fines affect people with different incomes? Cities and towns around the country rely on parking and speeding tickets to generate much-needed revenue. Unfortunately these fines can trap the neediest residents in a cycle of debt, especially when they’re compounded by monthly late fees.

In this lesson, students write, solve, and graph systems of linear equations to determine how long it takes to pay off a ticket and debate the fairest ways for cities to raise revenues without harming their poorest residents.

- Write and solve a system of linear equations and interpret the intersection in a real-world context
- Explore how changing the slopes and y-intercepts affects where (and if) two lines intersect
- Use a unit rate to create a table, graph, and equation
