Answer

The percent of change is -12.5%, so it is a percent decrease.

Work Step by Step

At the beginning, the client weighted 320 pounds. At the end, the client weighted 280 pounds. To find the percent change, we use this formula. Percent of change = $\frac{New\ amount\ -\ Original\ amount}{Original\ amount}$ $\times$ 100% Percent of change =$\frac{280\ -\ 320}{320}$ $\times$ 100% Percent of change = $\frac{-40}{320}$ $\times$ 100% -0.125 $\times$ 100 = -12.5%
