Answer 1

`\boxed{ \: company : B : \: } \\ \underline{ \boxed{ has \: a \: proportional \: relationship}}`

Explanation:

`let \: company : A : weight \: and \: cost\: be \to \: w_A \: and \:c_A \\ let \: company : B : weight \: and \: cost\: be \to \: w_B \: and \:c_B \\ \underline{\boxed{ \: company : A : \:} } \\ if \to \: c_A \infty w_A \\ c_A = k w_A \\but \to : \\ k = (c_A)/(w_A) = (10.55)/(1) \\ot= \: (10.85)/(2) \\ot= (11.15)/(3) \\ therefore \to : \\ \boxed{ \: company : A : \: } \\ \underline{ \boxed{ has \: no \: proportional \: relationship}} \\ \\ \underline{\boxed{ \: company : B : \:} } \\ if \to \: c_B \infty w_B \\ c_B = k w_B \\but \to : \\ k = (c_B)/(w_B) = (2.75)/(1) = (5.5)/(2) = (8.25)/(3) = 2.75 \\ hence \to : \\ \boxed{ \: company : B : \: } \\ \underline{ \boxed{ has \: a \: proportional \: relationship}}`
