Question I had a question in my class about percentage. There was a boatseller who needed some cash, so he sold two of his boats, both for $6000. After he realized he had made 20% on one of the sells and lost 20% on other..did he loose or break even?
Answer 6000 = x*1.20
6000 = y*0.80
Boat one was worth 6000/1.20 = 5000 so he made $1000 profit.
Boat two was worth 6000/0.8 = 7500 so he lost $1500. In the end, he lost $500.
This problem is my life when it comes to the stock market recently. Down 50% up 50% but net loss when it is all told! Bleh. C'est la vie!
