**After careful scrutiny, Robbin budgets $12/week for Wings ‘n’ Suds**

After careful scrutiny, Robbin budgets $12/week for Wings ‘n’ Suds. Consider the following: Graph and label the axes to show how much of each good Robbin is able to buy, if the price of buffalo wing is $0.50, while the price of Coca-Cola is $1.50. In order to attract more customers to Wings ‘n’ Suds , management decides to lower the price of Coca-Cola to a buck. Show what happens to Robbin’s budget line compared to (a). Instead of (b), assume there is a sudden shortage of buffalo wings available. Now, Wings ‘n’ Suds has to raise the price of a wing to $3. Show how this event changes Robbin’s budget line relative to (a). Robbin, after winning $1,000 in the Texas lottery, decides that she can now spend $36/week at Wings ‘n’ Suds. Show how this event changes Robbin’s budget line relative to (a). e. What combination of wings and Coca-Cola should Robbin buy in (a), (b), (c), and (d)?
