Section 1: Using [SOLVE j Effectively
Example: A leasing firm is considering the purchase of a
minicomputer for $63,000 and wants to achieve a 13% annual yield
by leasing the computer for a 5-year period. At the end of the lease
the firm expects to sell the computer for at least $10,000. What
monthly payment should the firm charge in order to achieve a 13%
yield? (Because the lease payments are due at the beginning of
each month, be sure to set flag 0 to specify beginning-of-period
payments.)
