Suppose coffee (F) and cream (C) are perfect, two-for-one
complements and Jack spends his budget of $12 per day on these two
goods. That is, assume that Jack likes one ounce of cream for every
two ounces of coffee. The price of cream is $2 per ounce. The price
of coffee is also $2 per ounce. (It’s a fancy coffee shop.) Jack’s
Utility function is U = min (F, 2C)
a. Find and graph Jack’s demand curve for cream. Assume the
price of coffee is still $2 and income is $12.
