qiufneg1990 那是个主谓！ 我到是认为princess的较好。

我觉着 businesses carry 不可数,所以 as much as.

princess

inventory
1.货物总单，清单（可数）
The company's inventory lists 2000 items.
an inventory of items in an estate
2.盘货（不可数）
The store was closed for inventory all week.
The inventory revealed that the store was overstocked.

inventory表示的是一个总值。其中应包括一些不可数的物品，所以用much较好。
这个纯粹为个人猜测。请牛人给出准确的解释！！
谢谢拉。
