Q18: GWD-4-4
A new hair-growing drug is being sold for three times the price, per milligram, as the drug’s maker charges for another product with the same active ingredient.

A.   as
B.   than
C.   that
D.   of what
E.   at which

答案选C，我看og一般用"two times","twice"等词来做比较时一般都接"as many/much as"的用法啊，本题的用法请同学们详解！谢谢了！

(a) and (b) are unidiomatic: (a) is wrong because the sentence doesn't contain "three times as much...", and (b) is wrong because the sentence doesn't contain "more".

(e) is bad diction: "the price at which the manufacturer charges" isn't right. you don't charge at a price; you just charge a price (for something).

(d), taken literally, has an absurd meaning: it says "the price of what the drug's maker charges".

times做比较时的用法
1）X times+as+adij./adv.+as
2）X times+the+n.
3）X times more than
