You can put this solution on YOUR website!
in april, 1995, the index was 124.2.
in april, 2000, the index was 150.4.

the difference is 150.4 - 124.2 = 26.2.

that's not the % difference.

that's the absolute difference.

take the absolute difference and divide it by 124.2 and you get .210950081.

multiply that by 100 and you get 21.0950081%.

that's the percent difference from 124.2.
