Expert Solution

Number of payments required to achieve future value = log [(FV × r/ PMT) +1] /log(1+r)
Future value FV                                    7,000.00
Rate per period r
Annual interest 6.5%
Number of payments per year 12
Interest rate per period 0.065/12=
Interest rate per period 0.542%
Payment per period PMT $                                   330.00
Number of payments = log [( 7000×0.00542/330) +1]/ long(1+ 0.00542)
=                                          20.13
Years                                            1.68
