TI-84 Plus CE Purchase Planning Formula and Mathematical Explanation
Our TI-84 Plus CE Graphing Calculator Staples Purchase Planner uses several formulas to give you a comprehensive overview of your potential purchase. These calculations help you understand the true cost and logistical aspects.
Step-by-Step Derivation:
- Discount Amount Saved:
Discount_Amount = List_Price × (Discount_Rate / 100)
This calculates how much money you save based on any percentage discount offered by Staples. - Price After Discount:
Price_After_Discount = List_Price - Discount_Amount
This is the cost of the calculator after any discounts have been applied, but before tax or warranty. - Sales Tax Amount:
Sales_Tax_Amount = Price_After_Discount × (Sales_Tax_Rate / 100)
This determines the amount of sales tax you will pay, based on your local tax rate. - Estimated Total Out-of-Pocket Cost:
Total_Cost = Price_After_Discount + Sales_Tax_Amount + Extended_Warranty_Cost
This is the final amount you will pay, including the discounted price, sales tax, and any optional extended warranty. - Estimated Delivery Date:
Delivery_Date = Purchase_Date + Shipping_Days
This estimates when your TI-84 Plus CE Graphing Calculator Staples order will arrive. Note that this calculator provides a simple addition of days and does not account for weekends or holidays for simplicity. - Effective Cost Per Year:
Cost_Per_Year = Total_Cost / Useful_Life_Years
This metric helps you understand the long-term value of your investment by spreading the total cost over the expected years of use.

| Variable | Meaning | Unit | Typical Range |

| List Price | Advertised price of the calculator at Staples. | USD | $120 – $180 |

- Staples Discount: 0%
- Optional Extended Warranty Cost: $19.99
- Estimated Shipping Days: 5 business days
- Planned Purchase Date: October 26, 2023
- Estimated Useful Life: 4 years
Outputs:
- Discount Amount Saved: $0.00
- Price After Discount: $149.99
- Sales Tax Amount: $149.99 × 0.065 = $9.75
- Estimated Total Out-of-Pocket Cost: $149.99 + $9.75 + $19.99 = $179.73
- Estimated Delivery Date: October 26, 2023 + 5 days = October 31, 2023
- Effective Cost Per Year: $179.73 / 4 = $44.93
Interpretation: Sarah will pay $179.73 in total, and her calculator should arrive by October 31st. Over four years, this breaks down to about $44.93 per year of use.

- Estimated Shipping Days: 2 business days
- Planned Purchase Date: November 10, 2023

Outputs:
- Discount Amount Saved: $149.99 × 0.15 = $22.50
- Price After Discount: $149.99 – $22.50 = $127.49
- Sales Tax Amount: $127.49 × 0.08 = $10.20
- Estimated Total Out-of-Pocket Cost: $127.49 + $10.20 + $0.00 = $137.69
- Estimated Delivery Date: November 10, 2023 + 2 days = November 12, 2023
- Effective Cost Per Year: $137.69 / 5 = $27.54
Interpretation: Mark saves $22.50 with the discount, bringing his total cost down to $137.69. Without the warranty, and with a longer useful life, the effective cost per year is significantly lower at $27.54.
