During a sale, for each shirt that Mark purchased at the regular price, he also purchased a shirt at half the regular price. How many shirts did Mark purchase during the sale?

(1) The regular price of each of the shirts that Mark purchased during the sale was $21.50.

(2) The total of the prices for all the shirts that Mark purchased during the sale was $129.00.

Ans:C

想請問的是，he also purchased a shirt at half the regular price.這句話是說他也買的「一件」半價的襯衫嗎？
不然我覺得這題應該是算不出來的，還是我想錯了....
先謝謝嚕～

好糟，不難的題目也看不懂....

是呀！purchased a shirt at half the regular price 購買一件shirt是半價的意思(在促銷的期間)

所以
(1)給了在促銷期間的regular price$ 21.5
故可得知促銷價為：21.5/2 (半價) =$10.75(每件)

(2)在促銷期間，總供花了$129
故129/10.75=12(件)

所以(1)+(2) 才可知充份的知道How many shirts did Mark purchase during the sale? 12件

以上 參考
