Answer 1

To find the percent change between two numbers (based off of 434.90, or the first number listed), we first find the difference between the two numbers. To do this, we subtract the first number from the second. Here, we have 573.90-434.90=139.  Then, we divide the difference by the original number, resulting in $\frac{139}{434.9} =0.3196137043$. Finally, we multiply that answer by 100 to turn it into a percentage, resulting in 31.96137043 as our percentage. This is a positive increase because our number is positive.
