Answer to Question 1
A
Answer to Question 2
The opportunity cost of commuting per month from Apartment 1 = 60 30 = 1,800.
Total monthly cost of renting Apartment 1 = 1,800 + 3,600 = 5,400.
The opportunity cost of commuting per month from Apartment 2 = 20 30 = 600
Total monthly cost of renting Apartment 2 = 600 + 4,500 = 5,100
Therefore, the individual chooses Apartment 2 as she incurs a lower cost if she rents Apartment 2 than when she rents Apartment 1.
