Consider the recurrence relation defined in Example 3.3. Suppose that, as in the example, you borrow $700, but you pay her back $100 each week. Each week, Ursula charges you 10% interest on the amount you still owe, after your $100 payment is taken into account. (a) Write down a recurrence relation for M(n), the amount owed after n weeks. 700 if n = 0 M(n) = 1.10 ]. (Min - 1) - 1) - 110 if n > 0 (b) How much will you owe after four weeks? $
