Practical Examples (Real-World Use Cases)
Example 1: Good Condition Calculator
A student is selling their **ti 83 plus calculator used** after finishing their final math class. It’s in good shape with a few minor scuffs and has the slide cover.
- Inputs: Base Price: $100, Condition: Good (0.85), Screen: Good (0.90), Accessories: Cover ($5).
- Calculation: ($100 × 0.85 × 0.90) + $5 = $76.50 + $5 = $81.50
- Interpretation: A fair asking price would be around $81.50. This is a significant saving for the buyer compared to a new unit, while the seller recovers a good portion of their initial investment.
Example 2: Fair Condition, No Accessories
Someone finds an old **ti 83 plus calculator used** in a drawer. It powers on, but has noticeable scratches on the body and screen, and the cover is missing.
- Inputs: Base Price: $100, Condition: Fair (0.60), Screen: Fair (0.65), Accessories: None ($0).
- Calculation: ($100 × 0.60 × 0.65) + $0 = $39.00
- Interpretation: The estimated **used TI-83 Plus calculator value** is $39.00. While much lower than a pristine model, it’s still worth selling, as many are willing to accept cosmetic flaws for a lower price.
