Aguy wants to sell a $1,600 watch. he raises the original price by 75% while putting a 75% off sign on it. is this a good idea ?

No; the 75% off sign implies that he is lowering the price, when he actually wants to increase the price.

No, because when he is raising the price by 75% he is adding more cost to the orignal price . He put a 75% which was not a good idea because that would mean the new price would be 75% of 1,600

Hope this helps!
