An economy package of cups has 210 green cups. If the green cups are 10% of the total package, how many cups are in the package?

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
