Final answer:
Barbara paid a total financed cost of $363,240 for her house.
Step-by-step explanation:
To find the total financed cost Barbara paid for her house, we need to calculate the original loan amount for the balloon mortgage.
Let's assume the original loan amount is represented by 'L'. The initial payments were $1026, which we can represent as a fraction of the loan amount:
$1026 = (3/27)L
By cross-multiplying, we get:
L = $1026 * (27/3) = $9182
Next, we calculate the new loan amount for the 30-year mortgage. The new payments were $1009, which we can also represent as a fraction of the loan amount:
$1009 = (1/360)L
By cross-multiplying, we get:
L = $1009 * 360 = $363,240
Therefore, the total financed cost Barbara paid for her house is $363,240.
