The algebraic expression for "the quotient of 77 and x" is

i think is g(1)=-1.

hope that i can

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
