The price of us tys stock fell from $35.76 to $ 29.24 . What is the percent of decrease in price?

One REALLY easy method of percent of change is old-new/old. So this is how you do it...
35.76-29.24/35.76=x
x=18.2%
I DID NOT make that up myself. My math teacher is a ''mathematician" so he taught his honors kids that. Wow I can't believe I remember that! I thought my brain would be mush by now, since I haven't even thought of the word school all summer. Lol hope that helps
