Ksivusya [100]

Answer:

Buffalo mild wings offers the lowest price per wing ($0.83).

Step-by-step explanation:

Let us find unit price per buffalo wing of each restaurant.

$\text{Unit rate for buffalo bills}=\frac{\$7}{8\text{ wings}}$

$\text{Unit rate for buffalo bills}=\frac{\$0.875}{\text{ wing}}$

Upon rounding our answer to nearest cent we will get,

$\text{Unit rate for buffalo bills}=\frac{\$0.88}{\text{ wing}}$

Therefore, buffalo bills offers each wing for $0.88.

$\text{Unit rate for buffalo mild wings}=\frac{\$10}{12\text{ wings}}$

$\text{Unit rate for buffalo mild wings}=\frac{\$0.83333}{\text{ wing}}$

Upon rounding our answer to nearest cent we will get,

$\text{Unit rate for buffalo mild wings}=\frac{\$0.83}{\text{ wing}}$

Therefore, buffalo mild wings offers each wing for $0.83.

$\text{Unit rate for wingers}=\frac{\$17}{20\text{ wings}}$

$\text{Unit rate for wingers}=\frac{\$0.85}{\text{ wing}}$

Therefore, wingers offers each wing for $0.85.

We can see that buffalo mild wings offers the lowest price per wing that is $0.83 per wing.
