To find the percentage decrease in the price of the house, you can use the formula for percentage decrease:
\[ \text{Percentage Decrease} = \frac{\text{Original Price} - \text{New Price}}{\text{Original Price}} \times 100 \]
In this case, the original price is $130,000 and the new price is $104,000.
-
Calculate the decrease in price: \[ 130,000 - 104,000 = 26,000 \]
-
Now, plug this decrease back into the formula: \[ \text{Percentage Decrease} = \frac{26,000}{130,000} \times 100 \]
-
Simplify the fraction: \[ \frac{26,000}{130,000} = \frac{26}{130} = \frac{2}{10} = 0.2 \]
-
Now, convert to percentage: \[ 0.2 \times 100 = 20% \]
Therefore, the percentage decrease in the price of the house is 20%.
The correct answer is D. 20%.
