So in this one, we are DECREASING by 25%, so we say 25% of 820...
25% × 820 =
.25 × 820 = 205
Now since we are decreasing by 25%, we take our answer and subtract it from the original amount, 820.
820 - 205 = 615
820 decreased by 25% is
615.
I attached a picture with equation because it is easier than attempting to type it out.
