86.9%

Step-by-step explanation:

Using proportions to find the percentage.

The formal is normally partial/whole equals to percentage/100. In this case $565 is partial because the price increased. So it'll be $565/$650 = X/100. We're using X as a variable, for the unknown percentage. Then you'll have to cross multiply. 565 times 100 is 56,500, then divide it by 650. You'll then get, 86.9230769. Whenever you get results like these, you just need to round to the nearest hundredths place, which is 86.9%.
