# Combined PPF (Equal quantities) & Combined PPF (Specialization)

I am taking a beginner microeconomics course and I am stuck on a question. I understand all the parts but the question they are asking is slightly different than all of the examples in the text, video, and examples I have seen from a Google search.

I will put the question here and hope someone can help me.

1. There are two parts: a. Find the missing values for Combined PPF (Equal Quantities). b. Find the missing values for Combined PPF (Specialization).

2. The specialization part, I have been spinning my gears.

The following table shows production possibilities for Billy and Dale at the data required to answer the two questions at the bottom. I think I have the answer to question 1a correct. But the 1b, 'Combined PPF (Specialization)' I don't get it.

The following table shows production possibilities for Bily and Dale.

Billy Production Per Day Dale's Production Per Day
Cupcakes Muffins Cupcakes Muffins
0 12 0 16
1 9 1 12
2 6 2 8
3 3 3 4
4 0 4 0

Fill in the table below as follows

a. The first 2 columns represent joint production where Billy and Dale produce equal quantities.

b. The last 2 columns represent joint production where they each produce according to their comparative advantage (specialization).

Combined PPF (Equal quantities) Combined PPF (Specialization)
Cupcakes Muffins Cupcakes Muffins
0 28 0 ?
1 21 2 ?
2 14 4 ?
3 7 6 ?
4 0 8 ?

c. Plot the combined production possibility curves for both cases (equal quantities & specialization), with cupcakes on the horizontal axis, on the same graph).

I was able to piece together a graph but I am still unsure if it's correct. It look right, but I am second guessing myself.

Any help or a point in the right direction would truly help.

Thank you. Aaron
