Final answer:
The house's value decreased by $32,130 and the current value of the house is $324,870.
Step-by-step explanation:
To find the decrease in value, we need to calculate 9% of the original value of the house. This can be done by multiplying the original value by 0.09 (since 9% is equivalent to 0.09).
Decrease = $357,000 * 0.09 = $32,130.
The house's value decreased by $32,130.
To find the current value of the house, we subtract the decrease from the original value.
Current value = $357,000 - $32,130 = $324,870.
The current value of the house is $324,870.
