Is it a good idea to rent a storage unit? Americans love their stuff. There are more storage facilities in the United States than there are McDonald’s and Starbucks combined. But are people spending more on storage than their stuff is worth?

In this lesson, students write and solve multi-step equations to evaluate whether storage unit rentals are worth the cost and make recommendations for when people should store, sell, donate, or toss their unused stuff.

REAL WORLD TAKEAWAYS

  • The cost of storage can exceed the cost of the items stored; whether or not a storage locker makes (strictly financial) sense depends on the value of the items in it and how long they’ll be stored.

MATH OBJECTIVES

  • Write and solve inequalities (or equations) in the form of px + q = r

Appropriate most times as students are developing conceptual understanding.
