An office supply store received a shipment of boxes of pencils. How many pencils were in the shipment altogether? (1 gross = 12 dozen)
(1) The number of boxes of pencils in the shipment was 6 gross.
(2) There were 3 dozen pencils in each box of pencils in the shipment.
答案是C.....可是我覺得A就可以啦~!!
6gross=6x12dozen=72dozen...不就表示一個shipment中總共有這麼多dozen...所以所有的pencils等於72x12....所以A就可以解啦!!!
為什麼要C呢????
請幫忙一下!!謝謝
