你要多少钱的英文是"How much do you want?" 来源是从中文转译过来的。例句：

"I'm buying this book. How much do you want?"

"I want to pay you for the ride. How much do you want?"

"Can you tell me how much you want for this painting?"

需要注意的是，这句话在英文中有些不礼貌，因为在英文中，直接问别人要多少钱可能会被认为是不礼貌的。在日常交流中，更好的方式是间接问，例如："How much do you charge?" 或 "What's the price?"
