I would say D ..

56-28 divided by 28 is equal to 28/28 X 100

jimthompson5910 (jim_thompson5910):

The change in weight is 56 - 28 = 28 lbs Divide this change by the original weight: 28/28 = 1 Then multiply by 100 to get the percentage: 1*100 = 100% So this is a 100% increase (basically the weight doubled)
