Sofia only drinks a cup of coffee (C) with 2 teaspoons of sugar (S). She spends 15 dollars per week on both goods. Suppose the price of a cup of coffee is $ 1 and the price of one spoon of sugar is 25 cents.

a)       Write down Sofia’s utility function and draw her indifference map. What is the marginal rate of substitution between coffee and sugar?

b)      Write down her budget constraint. What is the slope of the budget line?

c)       Find the utility maximizing bundle for Sofia. Show her equilibrium on the graph.

At a local convenience store, you purchase a cup of coffee, but, at 98.4°C, it is too hot to drink. You add 34.3 g of ice that is −2.2°C to the 248 mL of coffee. What is the final temperature of the coffee? (Assume the heat capacity and density of the coffee are the same as water and the coffee cup is well insulated.)
