If Antonio bought two half-gallon cartons of ice cream during a special sale, what percent of the total regular price of the two cartons did she save?

(1) Antonio paid the regular price for the first carton and received the second carton for half the regular price.

(2) The regular price of the ice cream Antonio bought was $ 4.00 per half-gallon carton.

答案是 A ，為何不是C 呢?

只問你百分比，所以不用價錢也能算。
第二盒只要半價，所以省50%；加上第一盒的一起算，合計省25%。
