Practical Examples
Example 1: Single Student Purchase
A student buys one TI-84 Plus CE during a back-to-school sale with a 15% discount.
- Inputs: Base Price = $149.99, Quantity = 1, Sales Tax = 8.25%, Discount = 15%
- Calculation: ($149.99 * (1 – 0.15)) * (1 + 0.0825)
- Result: The final cost would be approximately $138.00.
Example 2: School Bulk Purchase
A high school purchases 25 TI-84 Plus calculators for its math department and is tax-exempt.
- Inputs: Base Price = $124.99 (for the standard TI-84 Plus), Quantity = 25, Sales Tax = 0%, Discount = 5% (bulk discount)
