The arithmetic, line by line
| Step | Calculation | Result |
|---|---|---|
| Discount rate as a decimal | 70 ÷ 100 | 0.70 |
| Discount amount | $149.99 × 0.70 | $104.99 |
| Final price | $149.99 − $104.99 | $45.00 |
| Price paid, share of original | $45.00 ÷ $149.99 × 100 | 30% |
At $1.50 per percentage point, the 5-point move up to 75% changes the saving by $7.50 on a single unit. Two units bought at 70% save $209.98 between them, which is $97.49 more than one unit at 75% ($112.49) — quantity and discount rate are separate levers and they do not trade evenly.

Frequently asked
What is 70% off $149.99?
$45.00. The discount is 70% of $149.99, which is $104.99, and that comes straight off the price: $149.99 − $104.99 = $45.00.
How much do I save at 70% off $149.99?
$104.99 on a $149.99 item, which is the 70% that comes off before the till total of $45.00. The share you still pay is 30%, and sales tax is charged on that smaller figure rather than on the original.
Is 70% off plus another 70% off the same as 140% 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 $48.60 on a $45.00 subtotal, not 8% of $149.99. There are exceptions for manufacturer coupons and mail-in rebates, but a shelf discount is applied first.
