Lesson 3: More Costs of Running a Restaurant

This lesson is optional. In this lesson, students apply expressions and signed numbers to the context of balancing projected income and expenses for a restaurant. Students decide how to model these incomes and expenses in their calculations (MP4).

As with all lessons in this unit, all related standards have been addressed in prior units. This lesson provides an optional opportunity to go deeper and make connections between domains.
