Close cost gap

In principle it might be used to reduce the cost gap. However I don't have Kaplan books and only have the BPP Revision Kit, so I do not have the questions you refer to.

This question would not ask for 2 ways. Rent is a fixed cost and although always they would look for ways of reducing the rent expense, it is not a specific cost of the Wizzie. They make other models and the rent cost is absorbed over all of them.
