Please help if you can! Will give brainliest! M<1 or M<2

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

d. you cannot tell because there are no values shown.

the answer to 1/4x+5/3x-4=2-1/12x is x=3

hope this if needed hmu
