In order to make some home improvements, a home owner spent $24,000. He paid 18% as a down payment and financed the balance of the purchase with a 36month fixed installment loan with an APR of 4.5%. Determine the home owner's total finance charge and monthly payment

% Financed = 100%  18% = 82%.
Amt. Financed = $24,000 * 0.82 = $19,680.
Pt = Po*r*t / (1  (1+r)^t).
r = 4.5% / 12 = 0.375% = 0.00375 = Monthly % rate expressed as a decimal.
Pt=(19680*0.00375*36)/(1(1.00375)^36,
Pt=2656.80 / 0.126063452 = $21,075.10.
Int.=Pt  Po=21075.10  19680=$1395.10
Monthly Payments=21,075.10 / 36 = $585.42.
