In this unit, students choose and use mathematics to model a problem situation.
Students are presented a scenario based on the work of Italian physicist Enrico Fermi. In the scenario, Emily has stored $24,400 in dollar bills under her mattress because she doesn’t trust banks. Emily’s daughter convinces her that millions of bed bugs may be eating her money, so Emily decides to remove the money from under the mattress and take it to the bank. Students must determine how many inches the mattress will be lowered when the money is removed and whether the suitcase selected to take the money to the bank will be big enough to accomplish the task.
