Worked Examples

Example 1: California Purchase

Item Price: $100.00

State: California (7.25% sales tax)

Discount: $10.00

Subtotal = $100.00 - $10.00 = $90.00

Sales Tax = $90.00 × 7.25% = $6.52

Total Cost = $90.00 + $6.52 = $96.52

Example 2: New York Purchase

Item Price: $75.00

State: New York (8.875% sales tax)

Discount: $5.00

Subtotal = $75.00 - $5.00 = $70.00

Sales Tax = $70.00 × 8.875% = $6.21

Total Cost = $70.00 + $6.21 = $76.21
