How do i write an inequality for this sentence? just number 4

n<0

Step-by-step explanation:

Like all of the other ones, you would just follow what it says.  In this case though you have to think a little harder.  If "n" is negative, what is a negative less than... 0. :)

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
