老师你好，请问为什么不乘以50000呢
NO.PZ2019052801000039问题如下 A farmer plans to sell 50,000 tons of soybeans in six months, he cis to short futures contracts to hee against the priline. The current priof soybeans is $ 508/ton, the contrasize is 100 tons, the storage cost for the soybeans is 1.5% per year. The continuously compounrate is 5%, what's the prifor the futures contra? A.$35412.B.$76634.C.$50217.$52478.is correct. 考点远期合约定价解析FP =S0e(r+C)×T=508e(0.05+0.015)×0.5=524.78FP\;=S_0e^{(r+C)\times T}=508e^{(0.05+0.015)\times0.5}=524.78FP=S0e(r+C)×T=508e(0.05+0.015)×0.5=524.78x100 tons per contra= $52478红色圈出来的是老师上课讲的公式，在这种离散情况下，PVCost在t0时刻到底怎么求，是不是题目得告诉具体cost金额，那除以的利率和时间呢？连续函数怎么用上面这个公式类似推导出来

A.$35412. B.$76634.
