At the age of 6, Travis' father gave him his baseball card collection. Now, Travis collects baseball cards. He collects an average of 500 cards a year. The collection that Travis received from his father had 3,500 cards in it. How old will Travis be when he has 6,000 cards in his collection?

incomplete question. how do you expect anyone to you when you do not post the question in its entirety?

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540
