The arithmetic, line by line
| Step | Calculation | Result |
|---|---|---|
| Discount rate as a decimal | 75 ÷ 100 | 0.75 |
| Discount amount | $79.99 × 0.75 | $59.99 |
| Final price | $79.99 − $59.99 | $20.00 |
| Price paid, share of original | $20.00 ÷ $79.99 × 100 | 25% |
At $0.80 per percentage point, the 5-point move down from 70% changes the saving by $4.00 on a single unit. Two units bought at 75% save $119.98 between them, which is $63.99 more than one unit at 70% ($55.99) — quantity and discount rate are separate levers and they do not trade evenly.

$20.00. The discount is 75% of $79.99, which is $59.99, and that comes straight off the price: $79.99 − $59.99 = $20.00.
How much do I save at 75% off $79.99?
$59.99 on a $79.99 item, which is the 75% that comes off before the till total of $20.00. The share you still pay is 25%, and sales tax is charged on that smaller figure rather than on the original.
Is 75% off plus another 75% off the same as 150% off?

Does sales tax apply before or after the discount?
After, in every US state that taxes the sale. Tax is charged on what you actually pay, so at 8% you owe $21.60 on a $20.00 subtotal, not 8% of $79.99. There are exceptions for manufacturer coupons and mail-in rebates, but a shelf discount is applied first.
