How do I find the principle loan amt, monthly payment, interest paid, and total purchasing cost when all I have is negotiated price, 8% APR, 3yrs, and a $1,000 down payment?????!!!

You can use the interest formula for finding the principle amount. It is as follows:

P= I/rt

where

p is principal amount

I is interest amount

r is rate of interest

and T is the time for investment

P= I/rt

where

p is principal amount

I is interest amount

r is rate of interest

and T is the time for investment
