Your lease calls for payments of $500 at the end of each month for the next 12 months. Now your landlord offers you a new 1-year lease which calls for zero rent for three months, then rental payments of $700 at the end of each month for the next 9 months. You keep your money in a bank time deposit that pays a simple annual rate of 5%. By what amount would your net worth change if you accept the new lease? (your return per month is 5%/12 = 0.4166667%)
