Finding the percent of change is using the ratio of the amount of change to the original amount. The increased amount is really the percent of increase. $7.25-$6.88 = $0.37 Then you divide by the Original amount. $0.37/$7.25 = 0.0510 Multiply by 100 to find the percentage .0510 = 5.10 which rounds ?
