I need help with this question :)

what is your question I wonder

the reason why your question keeps getting deleted because this is not a school related question : )

i will answer your question though.

i never tried church's

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
