Answer:
$1049.09
Step-by-step explanation:
The present value of the balloon payment is ...
$20,000/(1 +.06/12)^(12·10)) = $10,992.65
So, the effective amount of the loan is ...
$105,487.80 -10,992.65 = $94,495.15
The amortization formula gives the payment as ...
A = P(r/n)/(1 -(1 +r/n)^(-nt)) = $94,495.15(.06/12)/(1 -(1 +.06/12)^(-12·10))
= $94,495.15(.005)/0.450367 = $1049.09
The monthly payment is $1049.09.
