Tony bought 3 tickets to a concert for $78. how much will it cost for 6 tickets to he concert of all tickets have the same unit price?

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
