A delivery service charges $0.02 per ounce for the first 16 ounces of a shipment and $0.15 for each additional ounce of the shipment,(1pound=16ounce)

比较:

the delivery charges for x shipments weighing a combined total of 25 pounds vs 567.00

答案是D,不太理解,虽然我知道这里面x是未知的,不过根据我的理解,就算是按照最贵的价格0.02 per ounce来运送,最高收费也只有0.2*25*16<567. 难道是我理解错题意了?莫非题目中暗含了minimum charge per shipment这种类似的信息吗?
