A savvy shopper combines a 25% off coupon with the store’s existing 25% off sale. Ignoring sales tax, how much of the base price should the shopper expect to pay?

The sale first reduces the base price to 75% of its original amount. The coupon then takes 25% off that reduced price, so the shopper pays 75% of 75%: 0.75 × 0.75 = 0.5625, or 56.25% of the base price. The correct choice is 56.25%.
