  Apartment Monthly Commuting Time (hours) Rent ()
  1 60 2,800
  2 90 2,200
  3 120 1,500

Answer to Question 1

Direct cost of renting Apartment 1 = 2,800
Indirect cost of renting Apartment 1 = 60  20 = 1,200
Total cost of renting Apartment 1 = 2,800 + 1200 = 4,000

Direct cost of renting Apartment 2 = 2,200
Indirect cost of renting Apartment 2 = 90  20 = 1,800
Total cost of renting Apartment 2 = 2,200 + 1,800 = 4,000

Direct cost of renting Apartment 3 = 1,500
Indirect cost of renting Apartment 3 = 120  20 = 2,400
Total cost involved in renting Apartment 3 = 1,500 + 2,400 = 3,900

Direct cost of renting Apartment 4 = 1,400
Indirect cost of renting Apartment 4 = 150  20 = 3,000
Total cost involved in renting Apartment 4 = 1,400 + 3,000 = 4,400

From the above estimations, the total cost is least if the individual rents Apartment 3. Hence, renting Apartment 3 is optimum for the individual.
