The arithmetic, line by line
| Step | Calculation | Result |
|---|---|---|
| Discount rate as a decimal | 20 ÷ 100 | 0.20 |
| Discount amount | $149.99 × 0.20 | $30.00 |
| Final price | $149.99 − $30.00 | $119.99 |
| Price paid, share of original | $119.99 ÷ $149.99 × 100 | 80% |
At $1.50 per percentage point, the 5-point move up to 25% changes the saving by $7.50 on a single unit. Two units bought at 20% save $60.00 between them, which is $22.50 more than one unit at 25% ($37.50) — quantity and discount rate are separate levers and they do not trade evenly.

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 $129.59 on a $119.99 subtotal, not 8% of $149.99. There are exceptions for manufacturer coupons and mail-in rebates, but a shelf discount is applied first.
