问题如下：
Question
A market study conducted by a distributor provides the following exchange rates:
选项：
A.3.00% B.6.8% C.9.8%.解释：
Solution Exchange Rate Calculations
Spot Rate of C/D= 2.28*1.42/1.03=3.1433
Expected Spot Rate of C/D=2.26*1.4/1.08=2.9296
To determine the depreciation of the D relative to C, we have:
2.9263÷3.1433 −1=-6.8%
民币兑美元即期汇率= 2.28*1.42/1.03=3.1433
C/D预期即期汇率=2.26*1.4/1.08=2.9296
D相对于C的贬值: 2.9263÷3.1433−1 = -6.8%
看不懂现在的答案解析

嗨，从没放弃的小努力你好：
把汇率里的/看成除法，用代数运算就可以。
根据代数运算法则：
1）A/B *B/D = A/D
2）(A/D) ÷(A/C) = A/D * C/A = C/D
联系1）和2），得出：
C/D = (A/B) *(B/D) ÷(A/C)
代入数字：C/D spot = 2.28*1.42/1.03=3.1433
代入数字：C/D Expected = 2.26*1.4/1.08=2.9296
现在是3.1433，未来是2.9296，未来贬值幅度 = 2.9263÷3.1433 −1=-6.8%
----------------------------------------------加油吧，让我们一起遇见更好的自己！
