Emily goes camping on the weekend and eats marshmallows (M) and crackers (C) there. She wants to match 1 marshmallow with 2 crackers, but does not eat in different proportion. The price of a marshmallow is 10 cents and the price of a cracker is 5 cents, and she spend up to $3 in total.

1. Write down a utility function which represents Emily's preferences over marshmallows and crackers.

2. How many marshmallows and crackers is she going to consume? (Hint: the first-order conditions will not help; draw the budget constraint and the indifference curves and look at the highest one that intersect the budget constraint).

3.What is the exact value of Emily's indirect utility?
