求翻译和解答

Mr Huang sold his camera to a customer for $320 after giving him a 36% discount. Find the amount Joel had to pay if Mr Huang gave a discount of only $45 for a camera of the same model .

Answer 1

翻译：黄先生将他的相机以$320元卖给客户，折扣为36%。若同一型号的相机黄先生只给乔尔$45元的折扣，求乔尔需要支付多少钱。
求解：
相机原价 = 320/(1-36%) = 500 元
乔尔应支付价格 = 500 - 45 = 455 元

Answer 2

黄先生在打了6.4折后，将他的相机以320元卖给了他的客户。看一看在同样的交易模式下，黄先生只降价了45元的情况下，Joel需要付给黄先生多少钱才能得到相机。
