15.5%

Step-by-step explanation:

Subtract the original amount from the new amount to determine the difference. Then divide the difference by the original amount to get the decimal version of the changed percentage.

$161,700 (increased amount) - $140,000 (original amount) = $21,700 (difference)

$21,700 / $140,000 = 0.155 or 15.5%
