Suppose the following table shows you the utility from consuming quiche and bottles of wine:

Bottles of wine	Total Utility	Marginal utility	Marginal utility per dollar
0	0
1	190
2	370
3	490
4	550
5	570

Quiche	Total utility	Marginal Utility	Marginal utility per dollar
0	0
1	110
2	190
3	250
4	290
5	310

1. Suppose the price of wine is $10 per bottle and the price of a quiche is also $10. Complete the other two columns.
2. Suppose you are given $100. And the price of wine is $10 per bottle and the price of a quiche is also $10. What is the optimal combination of consumptions?
3. Suppose the price of wine increases to $15 per bottle. How does this change the optimal number of bottles of wine?
4. Use the results from 2 and 3 to draw the demand curve for wine.
