In a far away land of Plutonia, a sales tax is applied when one is buying goods or services. A little boy, Confusia, is buying lots of stuff and would like to figure out how much the tax is. All that he knows is that whatever the price is, the total amount that he has to pay is multiple of 25 cents. Based on the list of items bought (as expressed in the list of problems), please help Confusia to figure out the tax level in Plutonia. Note that the currency of Plutonia is Dollar and there are 100 cents in each Dollar.
