You can put this solution on YOUR website!
week 1 = 80
week 2 = 120
120 - 80 = 40
40 / 80 = 1/2 = .5 = 50%

the increase was 40.
the original amount was 80.
the percent increase was 40/80 = 4/8 = 1/2 = .5 * 100 = 50%.

the increase from the original amount has to be divided by the original amount to get the percent increase from the original amount.
