A house decreased in value from $250,000 to $210,000. By what percentage does it need to increase the order to return to its original value of $250,000?

The original value of the house is $250,000 and it decreased to $210,000.

To calculate the percentage increase needed to return to its original value of $250,000, we use the formula:

(Original Value - Current Value) / Original Value x 100

(250,000 - 210,000) / 250,000 x 100 = 40,000 / 250,000 x 100 = 0.16 x 100 = 16%

Therefore, the house needs to increase by 16% in order to return to its original value of $250,000.
