Answer:
a. This part can be drawn here, so I have attached it in the attachment. Please refer to attachment for this part of the question.
b. First blank = 13 marks
2nd Blank = Astronomy
c. Economics for 3 hours
Astronomy for 1 hour
d. In this case, Jade's Performance Possibility Frontier graph will shift to left. As obviously, she will get low marks in both exams if her laptop dies.
Explanation:
Jade have total 4 hours to study and have two exams of Economics and Astronomy. If she only studies Economics then she will lose marks in Astronomy and vice versa. So, she needs to plan wisely to gain optimum marks and this questions is all about the planning.
Solution:
a. This part can be drawn here, so I have attached it in the attachment. Please refer to attachment for this part of the question.
b. Supposing Jade spend first 2 hours studying economics.
It means from the data, she would obtain 90 marks in Economics.
Now, the other part is asking that, if she spends 3rd hour studying Economics then what is the opportunity cost of spending that hour. And how much marks she will compromise for the other subject
So,
Suppose, she spends that 3rd hour studying Astronomy. So, according to data given, she will acquire 13 marks in Astronomy. And it is exactly the opportunity cost of spending the third hour studying Economics.
First blank = 13 marks
2nd Blank = Astronomy
c. In order to maximize the score from the combination of exams, Jade need to study Economics for 3 hours which will give her total marks = 95 marks
and she need to study Astronomy for 1 hour which will give her total marks = 83 marks.
In this combination, she will get maximum marks = 95 + 83 = 178 marks
d. In this case, Jade's Performance Possibility Frontier graph will shift to left. As obviously, she will get low marks in both exams if her laptop dies.
It should be noted that when Jade spends the first two hours studying economics. The opportunity cost of spending the third hour studying economics is 4 points on her astronomy exam.
Opportunity cost simply means the real cost of a foregone alternative. It is what one leaves in order to do something else. Also, Jade should spend 3 hours studying Economics and 1 hour studying astronomy.
Lastly, when Jade's laptop dies and refuses to start up. All her notes and class materials (for both classes) are saved on its hard drive, the production possibilities curve will shift to the left because studying becomes more difficult.
