Example 3: Using the information from example 1, what monthly payment is
necessary to yield the lessor 15% annually if one payment is due at the time of

Assuming that the previous example was just solved, the keystrokes are as
follows:

Since this problem is an annuity due situation (one payment at the beginning of
the period) the calculation could also be done as follows:
