Question: You are considering buying a car from a local auto dealer. The dealer offers you one of two payment options:
• You can pay $30,000 cash.
• The "deferred payment plan": You can pay the dealer $5,000 cash today and a payment of $1,050 at the end of each of the next 30 months.
As an alternative to the dealer financing, you have approached a local bank, which is willing to give you a car loan of $25,000 at the rate of 1.25% per month.
a.  Assuming that 1.25% is the opportunity cost, calculate the present value  of all the payments on the dealer ' s deferred payment plan.
b.  What is the effective interest rate being charged by the dealer? Do  this calculation by preparing a spreadsheet like this (only part of the  spreadsheet is shown-you have to do this calculation for all 30 months):
                   D                       E                                        F                                 G                           H
2           Month        Cash payment              Payment Under             Difference             
                                                                              Deffered
                                                                        payment plan
3              0                 30,000                      5,000                        25,000               <-- =E3-F3
4               1                      0                        1,050                       -1,050                <-- =E4-F4
5               2                      0                        1,050                       -1,050
6               3                      0                        1,050                       -1,050
7               4                      0                        1,050                       -1,050
8               5                      0                        1,050                       -1,050
9               6                      0                        1,050                       -1,050
10             7                      0                        1,050                       -1,050
11             8                      0                        1,050                       -1,050
Now calculate the IRR of the difference column; this is the monthly effective interest rate on the deferred payment plan.
