    So if it were increase would I just add then divide by the original amount?

    5.7 / 8.8 = 65%

    35% + 65% = 100%

    . No, it is:
    New amount-original amount/ original amount, then multiply answer times 100%.

    OK I understand that but there is another problem that says the number increases in 10 years so I added 252+398=650 and took 650/252=2.5793 I didn't think to multiply by 10 because the answer my teacher gave us is 57.9% but I kept getting the 2 in front of it then when I multiply by 10 I get 25.7936 so I don't know how my teacher got to the 57.9%
