问题如下：
An issuer with limited cash flow is deciding which of its suppliers’ credit terms are least costly. Which of the following credit terms offered to the issuer by its suppliers have the lowest effective interest rate?
选项：
A.
1/10, net 50
B.
2/15, net 40
C.
3/15, net 60

The calculations for the cost of financing for each set of credit terms, expressed as an effective annual rate, are as follows:
计算器9的上方y^x可以用来连续计算吗？1/10 Net 50为例，是要先算100/99等于多少，再算365/40等于多少，再用两个的结果通过y^x计算吗？能否直接按100/99，y^x，365/40计算？
