This is a smaller discount, useful for checking whether a light coupon meaningfully changes the price.

This is a higher-ticket price, so the dollar savings matter more than the percent alone.

In decimal form, 10% is 0.10 of the original price, so the remaining price is 0.90 of $100.00.

Even a small coupon can be worth checking on a higher-ticket item because the saved dollars scale with the original price.
