Katie is in charge of buying juice for the teacher; s breakfast party if one teacher will drink between 18 and 22 ounces of juice and there are 32 teachers which is the best estimate for the amount of juice katie should buy?

So on average 20 ounces is drank per teacher so 20 ounces x 32 teachers = 640

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
