Even me who is uneducated about economics know about the art of jerking up the price of an item by a few times, then giving you a small part back. I’ll give you an example: the cost price of a handphone is $50. You sold it at $250, then you discount it by 50%, thus selling it at $125, but at the end of the day, you still make $75! Just that you make lesser, but you are selling it at 250% of the cost price!”
Are the parts in bold correct? If not, what are the correct words that should be used? Are there any other errors.
Thanks in advance.
