Unit 9, Lesson 2
Costs of Running a Restaurant (Optional)
Grade 7
Preparation
Lesson Narrative
In this optional lesson, students apply expressions and signed numbers to the context of balancing projected income and expenses for a restaurant. Then students perform a cost analysis on using reusable or disposable plates and forks. Through this lesson, students make sense of situations involved in running a restaurant (MP1). As students make decisions about running a restaurant, they construct arguments and critique others’ reasoning (MP3). This lesson relies on skills developed in Unit 5, Unit 6, and Unit 8.
- Create an equation to represent certain expenses for a restaurant, and interpret (orally and in writing) the solution.
- Determine whether or not a relationship is proportional and explain (orally) the reasoning.
- Determine whether or not a restaurant is making a profit using estimates of ongoing expenses, number of meals sold, average price per meal, and average cost per meal.
Let’s explore how much running a restaurant costs.
