Austin is filling shelves at a grocery store. With every carton of 12 cereal boxes, he can fill 60 cm of shelving. The rack has 10 m of shelving, but 2 m is already occupied with other products. Austin must use enough cereal boxes to fill the rack.

To find the total number of cereal boxes needed to use the whole rack, we just need to use the rule of three: If 12 cereal boxes occupies 60 centimeters of shelving, 800 centimeters would require how many cereal boxes

Therefore, Austing needs 160 boxes to complete the rack.

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
