Practical Examples
Example 1: A High School Student
A high school student purchases the TI-84 Plus CE for $150. They also buy a case and a charging cable for $30. After 4 years, they sell it for $70.
- Initial Investment: $150 + $30 = $180
- Total Cost of Ownership: $180 – $70 = $110
- Cost Per Year: $110 / 4 = $27.50
Example 2: A College Engineering Student
An engineering student buys the most expensive Texas Instruments calculator, the TI-Nspire CX II CAS, for $165. They invest in extra software and a protective case for $60. After 3 years of intense use, they sell it for $90.
- Initial Investment: $165 + $60 = $225
- Total Cost of Ownership: $225 – $90 = $135
- Cost Per Year: $135 / 3 = $45.00
