Convert the Cartesian equation x^2 + y^2 - 2x = 0 to a polar equation. r ^2 = 2cosθ r = 2sinθ r = 2cosθ

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
