We can use the formula for compound interest to find the total amount that Lisa paid in 3 years for the loan, with interest.
P = 16400 (the principal amount)
r = (674.35/month) / (12 months/year) = 0.05619 (monthly interest rate)
n = 3 years x 12 months/year = 36 (total number of payments)
Using the formula:
A = P(1 + r/n)^(n*t)
where A is the total amount paid, and t is the time in years.
A = 16400 (1 + 0.05619/12)^(12*3)
A = $24,703.60
So Lisa paid a total of $24,703.60 for the loan, with interest.
If Lisa had a better credit rating and made payments of $451.88 per month, then the total amount she would have paid in 3 years would be:
P = 16400 (the principal amount)
r = (451.88/month) / (12 months/year) = 0.03766 (monthly interest rate)
n = 3 years x 12 months/year = 36 (total number of payments)
Using the same formula:
A = P(1 + r/n)^(n*t)
A = 16400 (1 + 0.03766/12)^(12*3)
A = $18,866.80
So Lisa would have paid a total of $18,866.80 if she had a better credit rating.
The difference between these two amounts is:
$24,703.60 - $18,866.80 = $5,836.80
Therefore, the amount that Lisa paid more in interest because of her bankruptcy is $5,836.80.
The correct answer is A) $5,836.80.
