PART B
Selecting the televisions most suitable for my needs, I chose Hisense 32P4 32 Inch 81cm Smart HD LED LCD TV. Although my selected television is 5.5 stars, in comparison to the other televisions, they are both 6.0 stars, however, its energy consumption is the lowest out of all of them, 116 kWh per annum and its purchase price is the cheapest, retailing at $399. This appliance’s running cost for three years is $104.40. Thus, the total cost of its ownership is $503.40, saving $399.80 if I bought Sony KDL43W660F 43 inch 108cm Full HD HDR LED Smart TV and saving $533.80 if I bought TCL 50P6US 50 Inch 127cm Smart 4K QUHD LED LCD TV.

Selecting the refrigerators most suitable for my needs, I chose Electrolux ETE4607SA-R 460L Top Mount Fridge.

Despite the fact, you will not save in 3 years, however, you will in 10 years as the total cost of its ownership would be $2244 and Samsung’s total cost of ownership would be $2394, thus, saving $150.
