Who knows how to solve the navier stokes equation

Nobody on this website XD

answer: no

step-by-step explanation:

you are only given the cost not the amount of pounds.

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
