What 4x-2 any know :(

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

x= cost per bracelet

number of bracelets * x + shipping charge = total cost

so

9x+9=72
