im pretty sure it would be 5 am, hope that , and give brainliest and guys if this is right then press the button and give 5 stars

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
