Please show me how to solve the following answers:

1.             The restaurant serves two types of customers a month. Customer X and customer Y. There about 1000 customer X and 100 customer Y.  Customers Y are willing to pay each is $5 for a meal. Each X's willingness to pay is $10. Each will purchase only one meal. The restaurant's marginal cost per meal is constant at $3, and there is no fixed cost.

b.        If the restaurant charges $10, who will buy the meal and what will the restaurant's is profit be? How large is consumer surplus?

c.        Assuming the restaurant can price-discriminate between X and Y by requiring X to show their ID, charging them $5 and Y $10, how much profit will the restaurant make? How large is consumer surplus?
