Connor,

You can determine the percentage of increase ( or decrease) by setting up a simple proportion and then cross multiplying. The formula is:

difference between starting point and ending point/starting point = percentage/100 if you plug your numbers into this formula you would have:

434/2035 = x/100

you then cross multiply 2035x = 43400 ( you should be able to take it from here )

you then divide each side by 2035 to determine the value of x

you can use this method for any percentage of change problem

I hope this helps

2469 - 2035 =0 . 175779668 = 17.6 %

2469

Note:

Shifting decimal point twice to the right (multiplying by 100) , and % = 0.01 = 1/100 ( dividing by 100)
