The Cars For Kings Company is putting out the new models. They want to put a 4-digit number on the back of each new model car. They have decided to use only the numerals 2,5,7,8. Each numeral can only be used once in a number. How many different numbers can the Cars For Kings Company put on the backs of the new model cars?
