Mr. Hall discusses the financial liabilities that Jamie Lee and Ross would undertake with the triplets living in a college dorm room that are on top of the usual tuition and book expenses.

Assume that the triplets’ rent for the dorm room is $7,500 per student/per year, based on a double occupancy and a shared bathroom. What is the total amount that Jamie Lee and Ross would owe for the entire four years for the three to stay in the dorms?
