Charlie has 5 times as many stamps as Ryan. They have 1,608 stamps in all. How many more stamps does Charlie have than Ryan?

Charlie has 1072 more stamps than ryan. This is because if x represents the amount of stamps that ryan has, then 5x represents how many charlie has. set up an equation, and you get 5x+x=1608, because all together they have 1608. Then collect (combine) like terms and you get 6x=1608. Divide both sides by 6 and you get x=268. Therefore ryan has 268 stamps, and charlie has 5x268 stamps, or 1340 stamps, and to get how many for charlie has, subtract his by ryan's, and you get 1340-268=1072
