answer is. 200

ok my answrer is correct

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value

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
