Answer:
Kyle Parker of Concord, New Hampshire, has been shopping for a new car for several weeks and gone for the dealer loan
Adjusted APR (dealer financing) = 12 [(95 x 60) + 9] (2500 + 649) / 12 x 60 (60 + 1) [(4 x 37000) + (2500 + 649)]
Adjusted APR (dealer financing) = 3.25%
Where:
Y = 12
F = 2500 rebate + 649 monthly payment
D = 38000 -1000=37000
P = 60
Since APR (dealer financing) < APR (bank loan), dealer financing is a better option.
