Can someone explain this too me

mhm yah sure ill explain

i think is 3 and 6. this took me 10 min to think.hope to and hope that my answer is brainliest.(follow me )

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
