Sarah's craft project used pieces of yarn that are 1/8 yard long. she has a piece of ynr that is 3 yards long

stops on an even number.

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
