Answer:
Total production of bread will be 12 loaves, and the total production of cake will be 8 units
Explanation:
Firstly, let's calculate the comparative advantage of both Sarah and Kate. It is evident Sarah has absolute advantage over Kate. However, the difference is significantly lower when comparing cakes, rather then comparing their bread rates. It is evident the productivity would be maximized if Sarah produced just bread, and Kate produced just cakes. That means they would use their maximum capacity for those goods.
Therefore, the total daily production of bread would be 12 loaves (Sarah's capacity), while the total daily production of cake would be 8 units (Kate's capacity).
