If 3 1/2 cups of flour are used with 1 1/4 cups of brown sugar, how much sugar is used when 10 1/2 cups of flour is used?

529 and 531

step-by-step explanation:

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
