Practical Examples (Real-World Use Cases)
Example 1: A Student’s Back-to-School Purchase
A student is buying one TI-84 Plus CE for their upcoming calculus class. The price at Staples is $159.99. Their state has a 6% sales tax, and they have a 15% off coupon from a Staples flyer.
- Inputs: Base Price = $159.99, Quantity = 1, Sales Tax = 6%, Discount = 15%
- Calculation:
- Subtotal: $159.99
- Discount Amount: $159.99 * 0.15 = $24.00
- Taxable Amount: $159.99 – $24.00 = $135.99
- Sales Tax: $135.99 * 0.06 = $8.16
- Total Cost: $135.99 + $8.16 = $144.15
- Interpretation: The student’s final cost for the ti 84 plus ce graphing calculator staples purchase will be $144.15 after applying the coupon and tax.
