问题如下：
In previous
question the amount of the commodity being hedged is 200,000 units, and one
futures contract is on 5,000 units of the commodity. How many contracts should
be used in hedging? (Round to the nearest whole number.)
解释：
The number of contracts is 0.72*200,000/5,000= 28.8
or 29, when rounded to the nearest whole
number.
