In the ancient country of Roma, only two goods, spaghetti and meatballs, are produced. There are two tribes in Roma, the Tivoli and the Frivoli. By themselves, the Tivoli each month can produce either 30 pounds of spaghetti and no meatballs, or 50 pounds of meatballs and no spaghetti, or any combination in between. The Frivoli, by themselves, each month can produce 40 pounds of spaghetti and no meatballs, or 30 pounds of meatballs and no spaghetti, or any combination in between.
a. Assume that all production possibilities curves are straight lines. Draw one diagram showing the monthly production possibilities curve for the Tivoli and another showing the monthly production possibilities curve for the Frivoli.
[Answer Field]
