设新卖掉的hardback数量为X，即10X+36000=441000，求出x=40500，paperback为9x即364500

From the time the first paperback copy was sold until the last copy of the novel was sold 9 times as many paperback copies as hardback copies were sold Let x = number of hardback copies sold during this time So 9x = number of paperback copies sold during this time So, x + 9x = total number of copies sold DURING THIS TIME PERIOD A total of 441,000 copies of the novel were sold in all GIVEN: 36,000 hardback copies sold BEFORE the paperback version was issued. So, we get: 36,000 + x + 9x = 441,000 Simplify: 36,000 + 10x = 441,000 We get: 10x = 405,000 Solve: x = 40,500 This also means 9x = 9(40,500) = 364,500 So, 364,500 paperback copies were Answer: C

好多陷阱，一不小心就列了错的等式1⃣️36000之前就已卖完2⃣️总的卖出的数量为441000，这其中就包含了1⃣️

(x/4.5)+[(500-x)/3.5]=120 9 times as many paperback copies as hardback copies 也就是 pc=9hc pc+hc+36000=441000 即 9hc+hc+36000=441000 然后可以求出hc，然后就可以求出pc 主要是理解好倍数关系

在出版了36000个H copy之后， Paper都涌向了出版界，去寻找他们的梦想，出版界迎来了新时代。新时代里，P=9H。旧时代加新时代一共出版了P+H=441000。 441000-3600=9+1（比例）， 算一算，出版王的悬赏金是多少呢

请问为什么要减去36000之后再除以10的比例？我理解的题意是总共卖了441000，平装书是精装书的9倍，直接441000/10*9为E？错在哪里了？您能帮我指出来么？

要注意看清题干，36000是在paper发行之前出售的，而后面则是在发行开始到最终结束。 这种题就是文字游戏，稍不留神就采坑了
