The Horse Problem!
A man buys a horse for 50 dollars. Decides he wants to sell his horse later and gets 60 dollars. He then decides to buy it back again and paid 70 dollars. However, he could no longer keep it and he sold it for 80 dollars.
Did he make money? lose money? or break even? Explain why.
I was watching a Marilyn Burns video titles 'About Teaching Mathematics'. In this video, this particular question was taken to the 'street'. There were as many answers as there are strategies to solve it! Why is this problem such a problem for so many?
