15. The cost of producing radios in Country Q is ten percent less than the cost of producing radios in Country Y.
even after transportation fees and tariff charges are added, it is still cheaper for a company to import radios from
Country Q to Country Y than to produce radios in Country Y.
The statements above, if true, best support which of the following assertions?
A. labor costs in Country Q are ten percent below those in Country Y.
B. importing radios from Country Q to Country Y will eliminate ten percent of the manufacturing jobs in Country
Y.
C. the tariff on a radio imported from Country Q to Country Y is less than ten percent of the cost of
manufacturing the radio in Country Y.
D. the fee for transporting a radio from Country Q to Country Y is more than ten percent of the cost of
manufacturing the radio in Country Q.
E. it takes ten percent less time to manufacture a radios in Country Q than it does in Country Y

虽然我做对了,可是还是觉得c答案也不很对,因为它还没有算交通费,公式应该

Q(COST)+.TA(tariff)+TR(transprotation)<Y(COST)

Q<10%Y怎么可以推出TA<10%Y???始终搞不明白????

Q(COST)比Y(COST)少10％，即使加上TA(tariff)+TR(transprotation)，仍然小于Y(COST)。当然推出

TA(tariff)+TR(transprotation)<10％*Y(COST)

原文：Q（COST）=（100-10)%Y(COST)，Q(COST)+.TA(tariff)+TR(transprotation)<Y(COST)

简单计算就知道C。
