亚当电子店在年度大促期间提供了全店 20% 的折扣。作为该店的会员，明辉在折后价的基础上还可以享受额外 10% 的折扣。他在大促期间买了一台相机。 明辉买这台相机付了多少钱？

1. Calculate the price after the first 20% storewide discount

$\text{Discounted price} = \char36{}2000 \times (100\% - 20\%) = \char36{}2000 \times 0.8 = \char36{}1600$

2. Calculate the final price after the additional 10% member discount

$\text{Final price} = \char36{}1600 \times (100\% - 10\%) = \char36{}1600 \times 0.9 = \char36{}1440$
