Answer:
$1003.82
Explanation:
You want the monthly payment on a $34,000 loan for 36 months at 4%.
Amortization
The amortization formula tells you the monthly payment on a loan of principal P at rate r for t months will be ...
A = P(r/12)/(1 -(1 +r/12)^-t)
For the given loan parameters, the payment will be ...
A = $34,000(0.04/12)/(1 -(1 +0.04/12)^-36) ≈ $1003.82
Your monthly payments will be $1003.82.
